Abstract: A second member has a larger heat capacity than a first member. Welding is conducted while moving a welding torch in a weaving motion so that the welding torch crosses a boundary position between the first member and the second member. During the weaving motion, the first member is subjected to first welding and the second member is subjected to second welding. The first welding includes at least the short-circuit welding. The second welding includes at least the pulse welding.
