Abstract

The invention relates to a welding structure of metal members, a method of welding metal members, and a power storage module. A welding structure (1) of metal members includes a first member (100) having a first opposing surface (110), a second member (200) having a second opposing surface (210), and a welding portion (300) fixing the first member (100) and the second member (200) to each other. A gap (400) is formed between the first opposing surface (110) and the second opposing surface (210). R1>R2 is satisfied where R1 represents a width of the welding portion (300) in the gap (400) and R2 represents a width of the welding portion (300) on the first opposing surface (110) of the first member (100). T2>T1 is satisfied where T2 represents a thickness of the second member (200) in the portion where the welding portion (300) is formed and T1 represents a thickness of the first member (100) in the portion where the welding portion (300) is formed. 0.8<=D1 / T1<=1.2 is satisfied where D1 represents a depth of the welding portion (300) in the second member (200) from the second opposing surface (210).

Description

technical field [0001] The present disclosure relates to a welding structure of a metal member, a welding method of a metal member, and an electric storage module. Background technique [0002] Patent Document 1 (Japanese Unexamined Patent Publication No. 2004-148334 ) discloses that a gap of a predetermined width is provided between upper and lower steel plates at a lap welded seam where steel plates are stacked and laser welded. [0003] Patent Document 2 (Japanese Unexamined Patent Application Publication No. 59-133985) discloses that in a welding method in which a member to be welded is welded by irradiating a laser beam to a welded part, welding is performed by providing a gap having a width smaller than the plate thickness of the member to be welded. . [0004] Patent Document 3 (Japanese Unexamined Patent Application Publication No. 2017-168349) discloses that in a welding structure for welding a bus bar to an electrode terminal of an electrical storage device, a con...
