Abstract

PURPOSE: To make it possible that, in the MIG arc welding using an inert gas as the main constituent, molten ball is not generated at the tip of wire and production of crater is prevented, by supplying a specified welding electric current at the time of welding completion.
CONSTITUTION: In the MIG arc welding using Al, Al alloy, stainless steel or Ni steel as the consumable welding wire, welding current Ia to be supplied until the welding work is completed is fixed to be sufficiently larger than spray translation critical welding current value (critical current value) until time t0 at which it is switched to crater filler current If. When time t0 comes, welding current Ia is changed to crater filler current If which is smaller than critical current value Ic, and at time t2 the welding current is again increased to final welding current Ie which is greater than the Ic by adjusting the output setter of welding machine. At the final stage, current Ie is interrupted by time t3, and generation of crater at places where welding is completed is prevented, and, at the same time, difficulty of arc start caused by large balls formed at the tip of wire is removed.
