Using AC to TIG weld aluminum evolved from the need to remove the oxide layer that forms on its surface. The EP portion of the AC cycle, in which electricity flows from the work to the tungsten, "blasts" off surface oxides. The EN portion of the cycle does the actual welding, directing...
This invention provides a new through weld method to carry out welding of a base metal made of aluminum or that of aluminum alloy using high energy beams wherein a shield gas ambience (an inert gas ambience) to cover a welding site in a submerged-scar is formed, even a shield gas ...
The welding experiments were carried out on 0.3 mm thick dissimilar materials like AA1100 aluminum sheet of grade H16 and UNS C27000 brass sheet of grade H04. The chemical composition of these two materials is represented in Table 1. For each weld trial, two coupon configurations were ...
