The ER5356 is the most widely used welding alloy and can be classified as general-purpose type filler alloy. Tig Rod 5356 is typically chosen because of its relatively high shear strength. The 5XXX alloy base material, welded with TIG rod 5356, with a weld pool chemistry greater than 3% Mg and service temperatures in excess of 65% are susceptible to stress corrosion cracking. The alloy is non-heat treatable.
