..., of the Engineered Materials Handbook. Corrosion of Welded Joints Aluminum and its alloys can be joined by as many or more methods as any other metal. The primary welding methods used are the gas-shielded arc welding processes, that is, gas metal arc welding (GMAW) and gas tungsten arc welding (GTAW...
