The welding of end ring of alternating current machine and the conducting bar is the key technology for manufacturing of asynchronous traction motor with high power. China South Locomotive and Rolling Stock Industry Corporation had taken this significative study as a key project for the manufacturing of alternating current machine. According to the welding of end ring of alternating current machine, the welding of copper and copper alloy is described in this paper. Results obtained in this study are as follows. 1.By the comparison of oxyacetylene gas brazing, induction brazing and resistance brazing, it was found that high-quality welding joint could be obtained by induction brazing, which also had the highest efficiency.

The relationships between welding pool width, wire extension and welding parameters including welding current duty ratio, base current, peak current, welding speed and wire-feeding speed were studied. Through large numbers of welding experiments, aluminum alloy pulsed MIG welding dynamic process were identified by the curve fitting method, and the mathematical models between welding current duty ratio, base current, welding speed, wire-feeding speed and wire extension were obtained, succeeding the model between the above parameters and weld pool width.
