METHOD FOR JOINING DISSIMILAR METALS, AND LASER WELDING DEVICE

Document Type and Number:

WIPO Patent Application WO/2019/026614

Kind Code:

A1

Abstract:

This method for joining dissimilar metals involves joining an Al-based parent material (2) comprising an Al alloy or pure Al and a Cu-based parent material (3) comprising a Cu alloy or pure Cu, wherein a welding material (5) comprising an Al alloy that contains Si and/or Cu is used to join the Al-based parent material (2) and the Cu-based parent material (3) through laser welding in which an irradiated portion that is irradiated by laser light is melted and solidified.
