Document Type and Number:

Japanese Patent JPH10128572

Kind Code:

A

Abstract:

To provide a welding method capable of stably and easily performing the welding of a super-thin metallic sheet.

A joining line is formed by the close bending on each of two super-thin metallic sheets 1-1, 1-2 to be joined with each other, the joining line is butted to each other and the welding is performed along the butt line. Or, a joining line by the close bending is formed on one super-thin metallic sheet, and a joining line and a return part 6 are formed by the triple close bending in the other super-thin metallic sheet, one super-thin metallic sheet is loaded on the return part 6 of the other super-thin metallic sheet, parts 2-1, 2-2 to be joined are butted to each other, and the welding 3 is performed along the butt lines.
