Abstract
A hybrid welding method capable of improving arc stability and improving the welding speed and the welding efficiency is provided. A hybrid welding method includes generating a TIG arc on a leading side in a welding direction and generating a MIG arc on a trailing side in the welding direction to weld a base metal, in which a TIG current is set to be higher than a MIG current so as to continuously generate arcs in a TIG electrode and a MIG electrode, and an absolute value of a distance from an intersection between a central axis of the TIG electrode and a surface of the base metal to an intersection between a central axis of the MIG electrode and the surface of the base metal is 20 mm or less.
