TITANIUM OR TITANIUM ALLOY MIG WELDING WIRE HAVING GOOD ARC STABILITY, AND MIG WELDING OF METHOD TITANIUM OR TITANIUM ALLOY BY USING THE WIRE

摘要

PROBLEM TO BE SOLVED: To provide a MIG welding wire and a method for MIG welding titanium and titanium alloy with stability and high efficiency.;SOLUTION: The surface of a titanium or titanium alloy wire for MIG welding (preferably, 1.6 to 2.0 mm of the outer diameter of the cross section) is coated with 510^-6 to 1.010^-3 g/mm² of Al particles having the average diameter 0.1 to 100 m and has good arc stability, and it is preferable that titanium or a titanium alloy is MIG welded by pulse welding current (for example, 300 A(peak current) 500 A and 2.0(peak current)/(base current)5.0).;COPYRIGHT: (C)2004,JPO
