| Abstract: | A modulated pulse microplasma arc welding power supply is developed by using high frequency pulse technology because of its function of self compacting and its feature of stability. The power supply has a function of regulating the thermal input to weld through the low frequency pulse modulating the high frequency pulse. And its arc also has a high intensity of eneergy, a low unload voltage, and a function of welding current increase in the initial duration and decrease in the duration close to ending. It is adequately used to the welding of metal sheets made of the copper alloy, titanium alloy, stainless steel and so forth. |
