In general, it is desirable to finish the weld quickly, before a large volume of surrounding metal heats up and expands. The welding process used, type, welding current and speed of travel, thus, affect the degree of shrinkage and distortion of a weldment. The use of mechanized welding equipment reduces welding time, metal affected zone and consequently distortion. This article helps to define ...

Abstract The so-called hairpin winding technology, which is specially tailored to electrical traction components, deploys rectangular plug-in copper wires in the stator. fusion welding of adjacent wire ends associated with challenges due high thermal conductivity as well porosity formation copper. During this study, electron beam (EB) electrolytic tough pitch (ETP) and oxygen-free electronic gr...
