Is professional recognition in plastic surgery related to activity in research

OBJECTIVE: To evaluate the relation of medical research, with the participation of prominent plastic surgeon in Congress.METHODS: We reviewed the scientific programs of the last 3 Brazilian Congress of Surgery, were selected 21 Brazilian plástic surgeons invited to serve as panelists or speakers in roundtable sessions in the last 3 congresses (Group 1). We randomly selected and paired by other members (associates) of the Brazilian Society of Plastic Surgery, with no participation in congress as speaker (Group 2). We conducted a search for articles published in journals indexed in Medline, Lilacs and SciELO for all doctors selected during the entire academic career and the last 5 years from March 2007 until March 2012. We assessed the research activity through the simple counting of the number of publications in indexed journals for each professional. The number of publications groups was compared.RESULTS: articles produced throughout career: Group 1- 639 articles (average of 30.42 items each). Group 2- 79 articles (mean 3.95 articles each). Difference between medias: p <0.001.CONCLUSION: The results demonstrate that the Brazilian Society of Plastic Surgery seeking professionals with a greater number of publications and journals of higher impact. This approach encourages new members to pursue a higher qualification, and give security to congressmen, they can rely on the existence of a technical criterion in the choice of speakers.

Cyber warfare

A postgraduate seminar series with a title Cyber Warfare held at the Department of Military Technology of the National Defence University in the fall of 2012. This book is a collection of some of talks that were presented in the seminar. The papers address computer network defence in military cognitive networks, computer network exploitation, non-state actors in cyberspace operations, offensive cyber-capabilities against critical infrastructure and adapting the current national defence doctrine to cyber domain. This set of papers tries to give some insight to current issues of the cyber warfare. The seminar has always made a publication of the papers but this has been an internal publication of the Finnish Defence Forces and has not hindered publication of the papers in international conferences. Publication of these papers in peer reviewed conferences has indeed been always the goal of the seminar, since it teaches writing conference level papers. We still hope that an internal publication in the department series is useful to the Finnish Defence Forces by offering an easy access to these papers.

Det planlagda och det som visar sig : klasslärarstuderandes syn på undervisning i teknisk slöjd

Sloyd as an activity concretizes man’s ability to, with the help of mind and body, reshape materials into objects and change her conditions for survival. The sloyd actor outside school works when the spirit moves her, while the pupil in school is expected to sloyd regardless of motivation. Subject teachers become experts on sloyd in educational settings, while the qualification requirements may set the class teachers’ voluntariness within parenthesis. All class teachers qualify to teach all core subjects of the national curriculum in Finland from preschool to grade six. The aim of the current thesis is to deepen the knowledge on how the science of sloyd education can support class teacher students’ future teaching in sloyd. In the empirical part of the study, Swedish-speaking Finnish class teacher students’ views on technical sloyd as one of their future subjects for teaching are examined. The class teacher’s qualifying skills in teaching technical sloyd are expected to take shape during only a few ECTS study points. The teacher students’ experience of the subject from the pupil’s perspective is supposed to move into a budding teacher subject. In a research-based teacher education, self-reflection and reflection as a dialogue are extended aided by research results. Intuitive thinking interplays with rational thinking during this time. The teacher student’s approach to make use of the autonomous free space in teaching is, in the current thesis, as considerations where the individual weighs the pros and cons in relation to various phenomena in sloyd and the school overall. The basis for an individual autonomy is shaped and is expected to interplay on the common arena of autonomy. In the exercise of their profession, the class teacher teaching sloyd is expected to oscillate between the sloyd educational practice and theory. The first step in this movement within the teacher education is the coverage of a selection of theories during the studies. The empirical part of the study is carried out at two separate occasions with directed open-ended interviews with fifteen class teacher students in the beginning and end of their first year of study. The data was analysed with a hermeneutic approach and a qualitatively oriented approach to content analysis. The results are mirrored against theory within the science of sloyd education. The results show that class teacher students have a versatile view of educational sloyd. The overall results overthrow parts of the researcher’s pre-understanding. The viewpoint of the students seems to broaden from a merely manual activity to seeing sloyd as an educational activity. In order for the results to gain significance in the teacher education of the future, a line of reasoning is conducted in order to recommend an extended dialogue and thirteen possible themes for enriching discussions are put forth as a result of the present study. The extended dialogue focuses on that teacher education should make conscious ventures to create opportunities for the students to take part in effective discussions on the subject of sloyd, complementing the existing dialogue between the teacher educator and the students. This thesis lends support to reflections on the following aspects of educational sloyd in these dialogues: the reasons for why the sloyd subject exists, the ambitions of the subject, the content and organization of the subject for students as well as for the teacher educators.

Quality, Productivity and Economy in Welding Manufacturing - Case Study: West Africa

This thesis studies quality, productivity and economy in welding manufacturing in West African states such as Ghana, Nigeria and Cameroon. The study consists of two parts: the first part, which forms the theoretical background, reviews relevant literature concerning the metal and welding industries, and measurement of welding quality, productivity and economy. The second part, which is the empirical part, aims to identify activities in the metal manufacturing industries where welding is extensively used and to determine the extent of welding quality, productivity and economy measurements in companies operating in the metal manufacturing industries. Additionally, the thesis aims to identify challenges that companies face and to assess the feasibility of creating a network to address these issues. The research methods used in the empirical part are the case study (qualitative) method and the survey (quantitative) method. However, the case study method was used to elicit information from companies in Ghana, while the survey method was used to elicit information from companies in Nigeria and Cameroon. The study considers important areas that contribute to creating awareness and understanding of the current situation of the welding industry in West Africa. These areas include the metal manufacturing industrial sector, metal products manufactured, metal production and manufacturing systems deployed, welding quality, productivity and economy measurement systems utilized, equipment and materials on the markets, general challenges facing companies in welding operations, welding technology programs and research in local universities, and SWOT analysis of the various West African states. The notable findings indicate that majority of the companies operate in the constructionindustrial sector. Also, majority of the companies are project manufacturing oriented, thus provide services to customers operating in the growing industries such as the oil and gas, mining, food and the energy industry. In addition, only few companies are certified under standards such as ISO 9001, ISO 3834, and OHSAS 18001. More so, majority of the companies employ manual welding technique, and shielded metal arc welding (SMAW) as the commonly used welding process. Finally, welder salary is about € 300 / month as of June 2013 and the average operations turnover of medium to large companies is about € 5 million / year as at 2012. Based on analysis of the results of the study, it is noted that while welding activities are growing, the availability of cheap labor, the need for company and welder qualification and certification, and the need to manufacture innovative products through developmental projects (transfer of welding expertise and technology) remain as untapped opportunities in the welding industry in the West African states. The study serves as a solid platform for further research and concludes with several recommendations for development of the West African welding industry.

Limits of Meritocracy. How Fields of Study and Gender Segregation Affect Social Stratification in Finland

This dissertation critically reviews the idea of meritocracy from both a theoretical and an empirical perspective. Based on a discussion of classical texts of social philosophy and sociology, it is argued that meritocracy as a concept for social stratification is best compatible with the sociological tradition of status attainment research: both frame social inequality in primarily individualistic terms, centring on the role of ascribed (e.g., gender, social background) and achieved (e.g., educational qualifications) characteristics for determining individuals’ socioeconomic rewards. This theoretical argument introduces the research problem at the core of this dissertation: to what extent can the individualistic conception of social stratification be maintained empirically? Fields of study and their interaction with educational attainment levels play a prominent role in the analysis of this question. Drawing on sociological versions of segmented labour market theory, it is assumed that fields of study may channel individuals into heterogeneous political-economic contexts on the labour market, which potentially modify the socioeconomic benefit individuals derive from their qualification levels. The focus on fields of study may also highlight economic differentials between men and women that derive from the persisting segregation of men’s and women’s occupational and educational specializations rather than direct gender discrimination on the labour market. The quantitative analyses in this dissertation consist of three research articles, which are based primarily on Finnish data, but occasionally extend the view to other European countries. The data sources include register-based macro- and microdata as well as survey data. Article I examines the extent and the patterns of gender segregation within the Finnish educational system between 1981 and 2005. The results show that differences between men’s and women’s field specializations have for the most part remained stable during this period, with particularly high levels of gender segregation observed at lower educational levels. The focus in Article II rests on the effects of gender-segregated fields of study on higher education graduates’ occupational status. It is shown that fields of study matter for accessing professional jobs and avoiding low-skilled positions in Finland: at the early career stage, particularly polytechnic graduates from female-dominated fields are less likely to work in professional positions. Finnish university graduates from male-dominated fields were more likely than their peers with different specializations to work as professionals, yet they also faced a greater risk of being sorted into lowskilled jobs if they failed to make use of this advantage. Article III proceeded to analyse the joint impact of educational qualification levels and fields of study on young adults’ median earnings in Finland between 1985 and 2005. The results show that qualification levels do not confer a consistent benefit in the process of earnings stratification. Advanced qualifications raise median earnings most clearly among individuals specializing in the same field of study. When comparing individuals with different field specializations, on the other hand, higher-level qualifications do not necessarily lead to higher median earnings. Overall, the findings of this dissertation reveal a heterogeneous effect of education for achieving social positions, which challenges individual-centred, meritocratic accounts of social stratification and underlines the problematic lack of structural and institutional dimensions in the dominant account of social status attainment.

Lakisääteiset hitsaustyöt ja niiden laadunhallinta

Tässä diplomityössä selvitettiin UPM Kaukaan tehtailla esiintyviin lakisääteisiin hitsauskohteisiin liittyvää lainsäädäntöä ja lainsäädännön vaikutusta hitsaukselle. Lakisääteisiä hitsauskohteita ovat räjähdysvaaralliset tilat, painelaitteet, kemikaaliputkistot, kemikaalisäiliöt, maakaasulaitteet sekä kantavat teräsrakenteet. Diplomityössä selvitettiin lisäksi hitsauksen laadunhallintaa huomioiden korjaushitsaustyöt sekä uuden rakentaminen. Lakisääteet tuovat hitsauksen suorittamiselle usein tarkasti määritellyt velvoitteet koskien esimerkiksi dokumentointia, hitsaushenkilöstön pätevyyksiä, materiaaleja ja niin edelleen. Lakisääteet lisääntyvät jatkuvasti ja soveltamisalueet laajenevat, jolloin asioiden ylläpitäminen vaatii jatkuvaa seurantaa. Työssä luotiin ohjeistus koskien yleisesti hitsausta ja lisäksi käyttäjän ja omistajan velvoitteita koskevat ohjeet painelaitteista, maakaasulaitteista ja kemikaalilaitteista. Hitsauksen yleisohje koskee jokaista hitsaustapahtumaa korjaushitsauksesta uuden rakentamiseen. Ohje soveltuu lisäksi sopimusliitteeksi hitsaustyön tilauksissa.

Uraohjaus ja urasuunnittelu ammattikorkeakoulussa

Tutkimuksen tarkoituksena oli selvittää, millaista uraohjausta ammattikorkeakoulun tuutoriopettajat antavat ja millaista uraohjausta opiskelijat haluavat. Lisäksi tavoitteena oli selvittää, löytyykö opiskelijoiden koulutusalavalinnan perusteista yhteyttä uran suunnittelutaitoihin ja ohjauksen tarpeeseen, ja tunnistavatko tuutoriopettajat opiskelijoiden erilaiset uraohjauksen tarpeet. Tutkimuksen teoreettisissa rakenteissa hyödynnettiin kolmea postmodernia urateoriaa, jotka olivat Hodkinsonin ja Sparkesin (1997) uranvalinnan päätöksentekoteoria, Mitchellin, Lewinin ja Krumbolzin (1999) suunnitellun sattuman teoria ja Savickasin (2005) uran rakentamisteoria. Tutkimusympäristönä oli Satakunnan ammattikorkeakoulu. Tutkimus oli kaksivaiheinen. Ensimmäisessä vaiheessa kerättiin harkinnanvaraisesti valituilta tuutoriopettajilta (n=14) ja opintojensa eri vaiheissa olevilta opiskelijoilta (n=65) kirjoitettu aineisto. Kvalitatiivinen aineisto analysoitiin sisällönanalyysillä. Aineiston perusteella löydettiin kolmenlaisia urasuunnittelijoita: epävarmat, uteliaat ja tietoiset. Aineiston perusteella laadittiin kyselylomake tutkimuksen toisen vaiheen tiedonkeruuta varten. Tutkimuksen toisessa vaiheessa kerättiin opintojen eri vaiheissa olevilta opiskelijoilta kyselylomakekyselynä kvantitatiivinen aineisto (n=903), joka analysoitiin tilastollisin menetelmin. Koulutusalavalinnan perusteista elämäntilanne, alan mahdollisuudet, oma toive, kutsumus, aktiivinen tiedonhaku ja halu opiskella ammattikorkeakoulussa olivat yhteydessä opiskelijan hyvään urasuunnittelukykyyn. Näillä perusteilla koulutusalansa valinneita tietoisiksi luokiteltuja urasuunnittelijoita oli 72 % vastanneista. Alavalinnan perusteista sattuman, kavereiden, sukulaisten, lukion opinto-ohjauksen ja paikkakunnan perusteella koulutusalansa valinneet luokiteltiin epävarmoiksi urasuunnittelijoiksi, ja heitä oli 28 % vastanneista. Tulokset antavat ohjaajille tukea epävarman ja muita enemmän uraohjausta tarvitsevan opiskelijan tunnistamiseen ja heidän hops-prosessinsa tehostamiseen opintojen alusta asti. Lisäksi tulosten perusteella esitetään seuraavia suosituksia: tuutoriopettajille tulisi asettaa pätevyysvaatimukseksi ohjausalan opintojen suorittaminen; opiskelijoita tulisi ohjata tunnistamaan erilaisia satunnaisesti avautuvia mahdollisuuksia ja tietoisesti hyödyntämään niitä elämässään; uraohjaukseen tulisi kytkeä mukaan työelämäyhteistyö; ohjaajien tulisi tiivistää yhteistyötä toisen asteen ohjaajien kanssa, jotta opiskelijoiden koulutusalavalinnat onnistuisivat paremmin; uraohjausta tulisi antaa tulevaisuuden kvalifikaatioiden ennakoinnin ja elinikäisten oppimisvalmiuksien näkökulmasta.

Point Of No Return: Dope Sick Love and Reindeerspotting as Documentaries of Addiction

In this postgraduate thesis the focus is on two documentary films, Renaud Brothers's Dope Sick Love (2005) and Joonas Neuvonen's Reindeerspotting (2010). In both of these films, addicts are on limelight. The directors of both films follow addicts and their everyday lives on streets with handheld cameras. This thesis will analyze and compare the narratives of these addicts. Do these documentaries affirm to the existing conventions, according to which representations of addicts and addiction are always either miraculous survival stories or stories, which always end up in utter decadence. The main questions this thesis proposes, are how addicts and their narratives are being handled in the two case study films, and how the drug cultures depicted in the films differ from each other. What changes between New York City and Rovaniemi, Northern Finland, and what remains the same. The academic and theoretical framework of this thesis consists of Susanna Helke's doctoral thesis Nanookin jälki, where the history of documentary films' methods and approaches are discussed. Additionally, the thinking is heavily informed by such poststructuralist writers as Roland Barthes, Michel Foucault, Louis Althusser, Stuart Hall and Chris Weedon.

Prosessiautomaatio pinnankorkeusmittauksen koelaitteistoissa

Pinnankorkeuden tunteminen kiehutusvesireaktorin painesäiliössä on erittäin tärkeää sen turvallisuusvaikutusten takia. Pinnankorkeutta mitataan vesipatsaiden korkeutta havaitsevien paine-eromittausten avulla. Säteilyturvakeskuksen YVL-ohjeiden mukaan turvallisuuteen vaikuttavien mittausten täytyy noudattaa moninkertaistus- ja erilaisuusperiaatteita. Yleensä erilaisuusperiaatetta on toteutettu käyttämällä erityyppisiä paine-eromittareita, mutta erilaisella fysikaalisella toimintaperiaatteella oleva mittaus olisi parempi ja toteuttaisi paremmin erilaisuusperiaatetta. Uimurikytkin olisi tällainen fysikaalisesti eri periaatteeseen perustuva pinnankorkeuden mittauslaite. Ydinvoimalaan tarkoitettu teknologia tulee kelpoistaa riippumattoman tahon toimesta ennen käyttöönottoa. Kelpoistamiskokeita varten Lappeenrannan teknillisen yliopiston Ydinturvallisuuden tutkimusyksikköön rakennettiin vuosina 2011–2013 kaksi koelaitteistoa. Näillä koelaitteistoilla tutkittiin uimurikytkimien toimintaa ja ominaisuuksia erilaisissa kiehutusvesireaktorin käyttötilanteissa. Koelaitteistot tarvitsivat toimiakseen automaatiojärjestelmät, jotka suunniteltiin pääosin noudattamalla suunnittelun elinkaarimallia sekä automaatiosuunnittelun sisältökokonaisuuksia. Automaatiojärjestelmien suunnittelu aloitettiin määrittelemällä koejärjestelyjen asettamat vaatimukset, jonka jälkeen tehtiin teknologiavalinnat. Seuraavaksi suunniteltiin automaatiojärjestelmien logiikkaohjelmistot, joiden kuvaukseen tämä työ pääasiassa keskittyy. Logiikkaohjelmistot toteutettiin graafisella National Instruments LabView -ohjelmointikielellä. Logiikkaohjelmistojen tuli hoitaa tiedonkeruuta, käyttöautomaatiota, turvallisuustehtäviä sekä kokeisiin liittyviä erikoistehtäviä. Ohjelmistot saatiin esikokeiden aikana toimimaan halutusti, ja varsinaiset kokeet voitiin suorittaa ilman merkittäviä ongelmia.

Critical infrastructure protection against cyber threats

A postgraduate seminar series with a title Critical Infrastructure Protection against Cyber Threats held at the Department of Military Technology of the National Defence University in the fall of 2013 and 2014. This book is a collection of some of talks that were presented in the seminar. The papers address origin of critical infrastructure protection, wargaming cyberwar in critical infrastructure defence, cyber-target categorization, supervisory control and data acquisition systems vulnerabilities, electric power as critical infrastructure, improving situational awareness of critical infrastructure and trust based situation awareness in high security cloud environment. This set of papers tries to give some insight to current issues of the network-centric critical infrastructure protection. The seminar has always made a publication of the papers but this has been an internal publication of the Finnish Defence Forces and has not hindered publication of the papers in international conferences. Publication of these papers in peer reviewed conferences has indeed been always the goal of the seminar, since it teaches writing conference level papers. We still hope that an internal publication in the department series is useful to the Finnish Defence Forces by offering an easy access to these papers.

Konepajan hitsaustuotannon kehittäminen kattavien laatuvaatimusten mukaiseksi

TIIVISTELMÄ Lappeenrannan teknillinen yliopisto Konetekniikan koulutusohjelma Voitto Kettunen Konepajan hitsaustuotannon kehittäminen kattavien laatuvaatimusten mukaiseksi Diplomityö 2015 167 sivua, 39 kuvaa, 26 taulukkoa ja 3 liitettä Tarkastajat: Professori Jukka Martikainen DI Pertti Kaarre Hakusanat: hitsaus, hitsauksen laatu, konepajan laadunhallinta, kattavat laatuvaatimukset, ISO 9001, ISO 3834, EN 1090 Keywords: welding, quality of welding, engineering workshop quality management, comprehensive quality requirements, ISO 9001, ISO 3834, EN 1090 Hitsaamalla liitetyt teräksiset rakenteet muodostavat ylivoimaisesti suurimman osan konepajatuotannosta. Niihin kuuluu esimerkiksi ajoneuvoja, koneita, laitteita, säiliöitä, siiloja, siltoja, mastoja, piippuja, tukirakenteita ja rakennusten runkoja. Tämän diplomityön tavoitteena on kehittää konepajan laadunhallinta sellaiseksi, että se mahdollistaa kattavien laatuvaatimusten täyttämisen hitsaustuotannossa. Laatuvaatimusten täyttämiseen pyritään käyttämällä hitsaustoimintojen standardia EN ISO 3834-2 sekä kantavien teräsrakenteiden standardeja EN 1090-1 ja EN 1090-2. Teräsrakenteiden suunnittelua ohjaa EN 1993 ja niiden toiminnallisia ominaisuuksia tuotestandardit, kuten terässavupiippu- ja säiliöstandardit. Kantavien teräsrakenteiden suunnittelua ja tuotantoa ohjaa myös seuraamusluokan CC, käyttöluokan SC ja tuotantoluokan PC kautta määräytyvä toteutusluokka EXC. Aikaisempaa enemmän tullaan panostamaan esimerkiksi asiakirjojen sähköiseen hallintaan, raaka-aineiden jäljitettävyyteen tuotteeseen, särmien ja kulmien muotoiluun, pintojen käsittelyyn, hitsien tarkastukseen, hitsaushenkilöstön pätevyyteen ja hitsaustuotannon tehokkuuteen. Saarijärven Säiliövalmiste Oy:n hitsauksen laadunhallinta sertifioitiin standardin ISO 3834-2 mukaan ja kantavien teräsrakenteiden FPC-järjestelmä standardisarjaa EN 1090 noudattaen. Samalla tehtiin päivitys laadunhallintajärjestelmään ISO 9001. Toteutus, joka tehtiin sovitussa aikataulussa, haastaa jokaisen toimijan konepajassa toiminnan, tuotannon ja tuotteiden laadun kehittämiseen uusia käytänteitä ja menetelmiä soveltaen. Kehitystoimien tuloksena toiminta on selkeämpää, ennakoitavampaa ja hallitumpaa, mikä lisää yrityksen toiminnan tuottavuutta ja kannattavuutta. Sertifioidut laatujärjestelmät ovat myötävaikuttaneet tilausten lisääntymiseen yrityksen kaikkien tuotteiden osalta.

Citations to papers from Brazilian institutions: a more effective indicator to assess productivity and the impact of research in graduate programs

A recent assessment of 4400 postgraduate courses in Brazil by CAPES (a federal government agency dedicated to the improvement of the quality of and research at the postgraduate level) stimulated a large amount of manifestations in the press, scientific journals and scientific congresses. This gigantic effort to classify 16,400 scientific journals in order to provide indicators for assessment proved to be puzzling and methodologically erroneous in terms of gauging the institutions from a metric point of view. A simple algorithm is proposed here to weigh the scientometric indicators that should be considered in the assessment of a scientific institution. I conclude here that the simple gauge of the total number of citations accounts for both the productivity of scientists and the impact of articles. The effort spent in this exercise is relatively small, and the sources of information are fully accessible. As an exercise to estimate the value of the methodology, 12 institutions of physics (10 from Brazil, one from the USA and one from Italy) have been evaluated.

Kraft recovery boilers – Principles and practice

This book was created as postgraduate lecture notes for Lappeenranta University of Technology's special course of steam power plants. But as with anything ever written the ideas shown have nurtured for a long time. Parts of these chapters have appeared elsewhere as individual papers or work documents. One of the most helpful episodes have been presentations and discussions during Pohto Operator training seminars. Input from those sessions can be seen in chapter firing. You who run recovery boilers, I salute you. The purpose of this text is to give the reader an overview of recovery boiler operation. Most parts of the recovery boiler operation are common to boilers burning other fuels. The furnace operation differs significantly from operation of other boiler furnaces. Oxygen rich atmosphere is needed to burn fuel efficiently. But the main function of recovery boiler is to reduce spent cooking chemicals. Reduction reactions happen best in oxygen deficient atmosphere. This dual, conflicting nature of recovery furnace makes understanding it so challenging. To understand the processes happening in the recovery furnace one must try to understand the detailed processes that might occur and their limitations. Therefore chapters on materials, corrosion and fouling have been added.

Kuparin hitsaus kattavilla laatuvaatimuksilla

Kuparin ja kupariseosten hitsaus eroaa merkittävästi esimerkiksi terästen hitsauksesta. Suuri lämmönjohtavuus, lämpölaajeneminen, pehmeneminen ja kuparin taipumus liuottaa kaasuja sulaan asettavat hitsaukselle haasteita. Kuparia on perinteisesti hitsattu kaasuhitsaamalla ja kaasukaarihitsausprosesseilla, mutta uudemmat menetelmät kuten laserhitsaus, elektronisuihkuhitsaus ja FSW-hitsaus tarjoavat uudenlaisia käyttökohteita korkealla laadulla. ISO 3834-2 asettaa noudatettavat vaatimukset hitsaustoiminnalle laatuvaatimusten ollessa kattavia. Ydinvoimalaitoksella hitsauksessa tulee lisäksi noudattaa Säteilyturvakeskuksen YVL-ohjeita, joissa on määritetty lisävaatimuksia liitosten materiaalivalinnoille, pätevöittämiselle ja tarkastamiselle. Tässä työssä tutkittiin kuparimetallien hitsauksen mahdollisuutta Loviisan ydinvoimalaitoksella juottamisen sijasta siten, että kattavat laatuvaatimukset täyttyisivät. Hitsauskokeissa ja laboratoriotutkimuksissa testattiin hitsausta erilaisilla hitsausaineilla ja hitsausprosesseilla. Koetulosten pohjalta toteutettiin hitsausmenetelmä deoksidoidun kupariputken ja tinapronssilaipan TIG-hitsaukselle.
