摘要： PROBLEM TO BE SOLVED: To provide an aluminum alloy for quench welding, which improves strength of the weld metal and a weld heat-affected zone without depending on increase of a Mg content, and can secure joint efficiency of 100% or higher, and to provide a welding method therefor. SOLUTION: The aluminum alloy for quench welding comprises, by mass%, 0.4-7.0% Mg, 0.05-1% Cu, further one or more elements of 0.8-2.5% Mn, 0.35-2.0% Cr, and 0.7-1.5% Fe, and the balance Al with unavoidable impurities. The alloy may contain one or more elements of 0.5-1.0% V, 2.0-2.5% Zr, and 3.0-3.5% Ni, as needed. The method for welding the aluminum alloy for quench welding is characterized by cooling the weld, after welding, from a melting point to 200°C at an average cooling rate of 500-10,000°C/second.
