Welding objective questions (mcq) and answers - MechanicalTutorialA: Aluminum Alloy castings scrapped in the foundry because of surface defects and lack of dimensional integrity can be salvaged by welding except if they present massive porosity. Gas tungsten arc welding GTAW with high frequency stabilized Alternating Current is normally used to repair sound castings. Inclusions should be prevented by taking care to avoid touching the surface with the pure tungsten electrode. Argon with or without helium can be used as a shield. Helium helps generating a hotter arc if necessary.
