PROBLEM TO BE SOLVED: To provide a welding method which can increase a weld strength, and a weld structure.SOLUTION: A weld structure 1 has plural weld objects 2, 4 which are joined with each other by a weld part 10 formed by laser welding. The weld part 10 has plural nuggets 12 which are formed along a virtual closed curve 14 on the weld object 2. Further, a ratio d/p of a diameter d of the nugget to a pitch dimension p between adjacent nuggets 12 is larger than 1/2 and not larger than 1. |
