Abstract: A welding method according to the present invention is a welding method for irradiating an object to be welded including a plurality of metallic plates that are stacked on each other with a high energy beam and performing welding. The welding method includes: forming a plurality of tack weld nuggets along a virtual closed curve on a part to be welded of the object to be welded; and forming a plurality of main weld nuggets so that the main weld nuggets overlap the plurality of respective tack weld nuggets.

Abstract: A welding method according to the invention is a welding method in which welding is performed by emitting a high-energy beam onto a welding object that includes a plurality of overlapped metal sheets. This welding method includes forming a tack weld nugget at a welding point on the welding object, and forming a plurality of final weld nuggets along a virtual closed curve that encircles the tack weld nugget, while leaving the tack weld nugget, at the welding point.
