Abstract

PURPOSE: To surely tack weld the member to be welded and a tack welding part by increasing the plasma gas to more than equal to the flow rate at the welding at the crater treating of welding.
CONSTITUTION: During the crater treatment in plasma arc welding, the plasma gas is again increased to a flow rate more than equal to the flow rate at the welding. The molten metal on the tack welding member 8 side is flowed and fused to the molten metal on the base metal 3 side, whereby the molten metal 10 made into one body is formed. This method makes it possible to surely tack weld the base metal 3 to be welded and a tack welding part 8 without addition of any fly wire.
