摘要： Provided is a manufacturing method for a joint body having a first metal member and a second metal member joined together by welding. With a density of the welding set higher than a density of the welding of other portions, the second metal member is bent within a plane by changing a positional relation of the second metal member relative to the first metal member in plan view.

摘要： A method for manufacturing a joint structure formed by joining a first plate-shaped member and a second plate-shaped member having a shape that is longer in a longitudinal direction than in a lateral direction includes overlapping the first plate-shaped member and the second plate-shaped member, after the overlapping, joining each of both edge portions of the second plate-shaped member by forming a weld metal along the longitudinal direction to the first plate-shaped member. The weld metal extends further outward in the lateral direction than the edge portions of the second plate-shaped member, in which the weld metal is formed by a hybrid welding in which a laser is added as a heat source during arc welding such that the weld metal extends around both of the edge portions of the second plate-shaped member along the longitudinal direction.
