Document Type and Number:
WIPO Patent Application WO/2019/021623
Kind Code:
A1
Abstract:
A method for producing a welded structure of metal members, which comprises: a preparation step wherein an Al alloy member that is composed of an Al-based alloy and a Cu member that is mainly composed of Cu are prepared; and a welding step wherein the Al alloy member and the Cu member are arranged to face each other, and the Al alloy member and the Cu member are welded with each other by irradiating the members with a laser beam from the Al alloy member side. The Al-based alloy contains, as an additional element, any one of Si in an amount of from 1% by mass to 17% by mass (inclusive), Fe in an amount of from 0.05% by mass to 2.5% by mass (inclusive) and Mn in an amount of from 0.05% by mass to 2.5% by mass (inclusive); and the irradiation conditions of the laser beam satisfy the output of 550 W or more and the scan speed of 10 mm/sec or more.
