An object of the present invention is to provide a hybrid welding method which can improve the stability of the arc, the welding speed, and welding efficiency, and the present invention provides a hybrid welding method in which a TIG arc is generated on the front side in the welding direction, and a MIG arc is generated on the back side in the welding direction in order to weld a welding base material, wherein electric current for the TIG welding is larger than electric current for the MIG welding; and an absolute value of the interval between an intersection of a center axis of a TIG electrode and a surface of the welding base material and an intersection of a center axis of a MIG electrode and the surface of the welding base material is 4 mm or less.
