Effect of Pulse Parameters on Metal Transfer of High Strength Austenitic MIG Wire

This paper studied the effects of pulse parameters(frequency,background current,duty cycle and wave shape) on the metal transfer of the high strength austenitic H08Cr18Ni27Mo6 MIG wire in the high speed video camera and Analysator Hannover.The results showed that the pulse parameters directly affect the metal transfer,especially the frequency,background current,and duty cycle.Using higher frequency and small duty cycle could obtain optimum metal transfer.
