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