Abstract
Disclosed are: a welding method capable of increasing the welding speed up to approximately 20 m/min., yet capable of producing good bead configurations and preventing welding defects such as blowholes; and a method of producing a welded member using the welding method. Specifically disclosed is a laser/arc hybrid welding method for butt-welding flat plates of stainless steel, titanium, or titanium alloy, or butt-welding both ends of a strip-shaped plate of stainless steel, titanium, or titanium alloy which has been formed into a tubular shape, wherein in the butt welding, the laser beam irradiation and the arc discharge trace the same welding line in such a manner that laser welding is followed by TIG arc welding.
