MIG/MAG welding of a range of metals. Pure argon is particularly effective for welding aluminium and its alloys. Also used for copper and nickel. Ferromaxx is a range of selected mixtures of argon, carbon dioxide and other gases to provide ideal arc conditions for spatter free welding of steels. Ferromaxx 7 is recommend-ed for carbon s355j2g3 plate Argon arc weldingVariables that Affect Weld PenetrationWith most arc welding processes, DC+ (direct current electrode positive) polarity produces more weld penetration, because more arc energy is focused into the base plate. Conversely, DC- (direct current electrode negative) polarity produces less weld penetration, because more arc energy is focused into the electrode and not into the base plate.TitaniumYou can weld it! - The FabricatorApr 06, 2004 · Argon's density is greater than air, so it tends to flow over the surface of a part in the same way water does. Where eddies occur, air can become mixed with the argon cover gas and create swirl patterns. What really separates titanium welding from most other types of GTAW is the need for an argon cover on the weld's back side.
