Abstract
PROBLEM TO BE SOLVED: To provide a laser jointing method that joints two materials while imparting a sufficient strength thereto and minimizing heat influence. SOLUTION: The method overlaps first and second materials (V1, V2) on each other and irradiates the surface of the first material (V1) with a laser light (103) from the side of the first material (V1). When jointing both materials (V1, V2), the method intermittently irradiating an overlapped part of the first and second materials (V1, V2) with the laser light while moving the laser light (103) to form a welding bead (1) on the surface of the first material (V1), wherein the length of the welding bead (1) is formed gradually shorter.
Claims11
A method of attaching a contact element to a conductor plate, comprising:
- welding the contact element to a conductive path of the conductor plate in a surface-mounted manner with a laser beam, the laser beam melts a material of the contact element only in a fused region, the fused region has a width smaller than a width of the contact element by a factor of ten or more, the fused region has a radius at a surface of the contact element that is greater than or equal to a width of the laser beam and less than or equal to three times the width of the laser beam;
- and
- flattening an end of the contact element before the welding step, the end of the contact element is welded to the conductive path in the welding step.
