The original objective of this project was to determine the effect of varying current intensity and electrode coating composition upon the spatter losses and porosity of arc welds made by alternating current. This subject was suggested by the Welding Research Council of the Engineering Foundation, which is a clearing house for welding research in order to avoid duplication of work.

In the field of copper metallurgy, the major changes effected in the original metallurgical scheme have been based largely upon the lowering in grade of copper ores, and the more particular demands of the fabricators of the metal. The former trend fostered the development of mineral beneficiation, which in turn caused the conversion from blast furnace to reverberatory furnace smelting.
