PROBLEM TO BE SOLVED: To provide a welding method that enables a bead shape to be obtained free from a stress concentration part, by dispensing with extra components, improving workability and enhancing quality of a weld zone, in welding metallic sheets with each other. SOLUTION: In one end of a first sheet member 1, an L shaped end part 1a is formed while, in one end of a second sheet member 2, a crown part 2b is installed that is formed extendedly in an L shaped end part 2a. The end faces 1c, 2c of both L shaped end parts 1a, 1b are abutted on each other, and the crown part 2b covers the L shaped end part 1a of the first sheet member, with the crown part 2b caulked to form an abutted part 20. Thereafter, this abutted part is fused. COPYRIGHT: (C)2011,JPO&INPIT
