文摘A new current wave controlling method for short circuit transition CO 2 welding using saturable inductor is put forward in this paper. Theory analysis and experiment results prove that the inverter's dynamic characteristics is greatly improved, the declining speed of current during liquid bridge neck shrinking is quicker, subsequently the energy accumulated in the bridge and the radius of the bridge before rupturing is reduced thus the low spatter result is achieved.
