Abstract
A welding method for welding an overlapping part of a first member and a second member includes: a first welding step of forming a friction-stirred part at a one-end-side spot being a spot that is closest to one end of the overlapping part by plunging a rotary tool into the one-end-side spot; a second welding step of forming a friction-stirred part at an other-end-side spot that is located away from the one-end-side spot and closer to the other end by plunging the rotary tool into the other-end-side spot; and a third welding step of forming a friction-stirred part at an intermediate spot located between the one-end-side spot and the other-end-side spot by plunging the rotary tool into the intermediate spot.
