Abstract
Provided is a manufacturing method for a joint body having a blank material plated with a metal material and a hoop material plated with a metal material joined together by placing the hoop material on the blank material and causing a laser oscillation system to irradiate a surface of the hoop material with laser light to form a joint portion including a line-shaped welded portion where the blank material and the hoop material are joined together. In this manufacturing method, the hoop material is supplied to be placed on the blank material and form a predetermined gap d between the blank material and the hoop material, and the hoop material is irradiated with a laser at a position where the predetermined gap d is located between the blank material and the hoop material to join the blank material and the hoop material together by laser welding.
