Abstract
A method of manufacturing a welded structure includes a preparation operation of arranging a first member to overlap a second member; a first welding operation of forming a first welding line on a first surface of the first member by welding a portion at which the first member overlaps the second member, the first surface of the first member being a surface of the first member facing the second member; a second welding operation of forming a second welding line on a second surface of the first member by welding the portion at which the first member overlaps the second member, the second surface of the first member being a surface opposite to the first surface; and connecting the first welding line to the second welding line.

A method of manufacturing a welded structure, the method comprising:
- a preparation operation of arranging a first member to overlap a second member;
- a first welding operation of forming a first welding line on a first surface of the first member by welding a portion at which the first member overlaps the second member, the first surface of the first member being a surface of the first member facing the second member, the first welding operation including forming a welding hole passing through the first member;
- a second welding operation of forming a second welding line on a second surface of the first member by welding the portion at which the first member overlaps the second member, the second surface of the first member being a surface opposite to the first surface, the second welding operation including filling the welding hole,
- wherein the second welding operation connects the first welding line to the second welding line such that a start point and an end point of the first welding line are connected to the second welding line and a start point and an end point of the second welding line are connected to the first welding line, so that the first welding line and the second welding line are connected to each other to form a closed-loop shape along a circumferential region of the first member.
A welded structure comprising:
- a first member including a first surface and a second surface opposite to the first surface;
- and
- a second member joined to the first surface of the first member,
- wherein the first member and the second member are joined to each other by a first welding line formed on the first surface of the first member and a second welding line formed on the second surface of the first member after the first welding line is formed, and
- wherein the first welding line and the second welding line are connected to each other by completion of the second welding line being formed such that a start point and an end point of the first welding line are connected to the second welding line and a start point and an end point of the second welding line are connected to the first welding line, so that the first welding line and the second welding line are connected to each other to form a closed-loop shape along a circumferential region of the first member.
A battery case comprising:
- a support panel including a first surface and a second surface opposite to the first surface;
- and
- a frame joined to the first surface of the support panel and disposed along a circumferential region of the support panel,
- wherein the support panel is joined to the frame by a first welding line formed on the first surface and a second welding line formed on the second surface after the first welding line is formed, and
- wherein the first welding line and the second welding line are connected to each other by completion of the second welding line being formed such that a start point and an end point of the first welding line are connected to the second welding line and a start point and an end point of the second welding line are connected to the first welding line, so that the first welding line and the second welding line are connected to each other to form a closed-loop shape along a circumferential region of the line and the second welding line form a closed loop along the circumferential region of the support.
