In this paper it constructs a phase shift to control zero-voltage-switching of high frequency inverter spot welding power supply topology structure. Through testing the former vice edge current, the system realizes the closed loop control. In this paper, it shows the working condition of main circuit modal. The experimental results proved the advantages of the topological structure.

The paper presents the results of studies improve efficiency of manual arc welding of austenitic steels. It is in arc welding of austenite steels the use of inverter power supply furthers obtaining more fine-grained structure of added metal and thermal impact zone, shortens thermal impact zone; that improves corrosion resistance of joint weld.
