|発明の名称||BUTT TIG WELDING METHOD|
PROBLEM TO BE SOLVED: To provide a butt TIG welding method with which butt TIG welding between a plated steel sheet and aluminum or an aluminum alloy can be satisfactorily performed.
SOLUTION: The edge parts of the plated steel sheet 10 and the aluminum or the aluminum alloy 12 are butted, an electrode is located at the part of an arrow B on the aluminum or aluminum alloy side so as to generate arc, and welding is started. After the start of the welding, the electrode is moved on a line L2 in the direction of a butt line A and also toward a line L1 parallel to the butt line A on the aluminum or aluminum alloy side. After that, a welding torch is moved in the direction of the line L1, and welding is performed. At this time, the fundamental data on pulse current obtained by sensitive pulsed current control welding are corrected for the faulty part in the welding result so as to obtain a welding program, and welding is performed while reproducing the welding program by an operator.
