PURPOSE:To provide an Al alloy filler metal having excellent mechanical properties and corrosion resistance without any weld crack, by adding specific amts. of Mg, Zr, Mn, Ti, B and Fe to Al. CONSTITUTION:A filler metal having the compsn. added with 3.0-6.0wt% Mg, 0.15-1.0wt% Zr, 0.05-0.3wt% Mn, 0.01-0.3wt% Ti, 0.0001-0.01wt% B, and 0.05-0.5wt% Fe to Al is used as a filler metal to be used for welding Al alloy members. A weld zone having excellent mechanical properties and corrosion resistance is obtd. without any weld crack. |
