Research on AC Short-Circuit Transfer Low-Energy Welding Technology

The one cycle AC short-circuit transfer welding method is a new type of low-energy welding method, which could flexible control the welding process on the energy distribution of basement material and wires by changing the time of the polarity of the EN. Tests showed that the 1.0mm thin sheet welding, and welding process stability, beautiful weld bead, and small spatter could be achieved successfully by this one cycle AC short-circuit transfer welding method.
