Abstract: A method of fusion welding structural members of an aluminum alloy parent metal having an essential composition of 0.8 to 7% copper, not more than 3% magnesium, 1.2% silicon, 1.2% manganese, 0.7% iron, 0.15% titanium, 0.15% vanadium, 0.25% zirconium, 0.25% zinc, 0.1% chromium, 0.02% cadmium, 0.05% others each, and 0.15% others total as impurities, balance aluminum, by forming a welded joint between the members with a filler metal having an essential composition of 5 to 7% copper, 1 to 2.5% magnesium, and 0.1 to 3.3% silicon, not more than 0.25% zirconium, 0.15 % titanium, 0.8% manganese, 0.7% iron, 0.02% vanadium, 0.25% zinc, 0.1% chromium, 0.05% others each, and 0.15% others total as impurities, balance aluminum. A method of fusion welding structural members of an aluminum alloy parent metal having an essential composition of 1.2 to 2.6% copper, 1.9 to 2.9% magnesium, and 5.1 to 6.7% zinc, not more than 0.35% chromium, 0.15% zirconium, 0.4% silicon, 0.5% iron, 0.3% manganese, 0.2% titanium, 0.05% others each, and 0.15% others total as impurities, balance aluminum, by forming a welded joint between the members with a weld filler metal having an essential composition of 5 to 7% copper, 1 to 2.5% magnesium, and 1 to 3.3% silicon, not more than 0.25% zirconium, 0.1% titanium, 0.8% manganese, 0.7% iron, 0.02% vanadium, 0.1% chromium, 0.05% others each, and 0.15% others total, balance aluminium.
