PROBLEM TO BE SOLVED: To provide a butt-welded joint having excellent corrosion resistance and capable of ensuring the joint strength and its joining method in the butt-welded joint of an aluminum alloy plate and a plated steel plate which are dissimilar materials from each other. SOLUTION: An aluminum alloy plate and a zinc alloy-based metal plated steel plate, or an aluminum alloy plate and an aluminum-plated steel plate are butted to each other and subjected to the arc welding. An aluminum-based welding wire is used therefor, and the targeting position of the wire is set in the range of 0.1-3.2 mm on the aluminum alloy plate side from the joining position, and the arc welding is performed from one side of a base material. The deposited metal is formed by melting an aluminum wire as a filler metal, an aluminum alloy plate and a plated layer, and covers a joined part. COPYRIGHT: (C)2009,JPO&INPIT |
