How To Weld Magnesium Alloy. The cleaned wire should be used on the same day within 10 days in dry weather. Weld-ing of aluminum and magnesium alloys with GTAW is relatively straight-forward provided that joints are adequately cleaned the wire is properly stored and shielding gas recommendations are followed.
This is exacerbated for alloy compositions with Ca additions that are inherently brittle. 1 High-quality cosmetic welds with smooth weld ripple can be obtained by using alternating current tungsten inert gas ACTIG welding that allows fragmentation of refractory oxides during the half cycle when the base becomes an electron-emitting cathode EP. Among these processes laser welding is paid more attention due to its advantages.
Gas tungsten arc is recommended for thinner materials and gas metal arc is recommended for thicker materials however there is considerable overlap.
