Characteristics and Applications
This aluminum alloy welding wire with high magnesium content contains trace elements of Mn, Cr and Zr, which helps to refine the weld microstructure and reduce the tendency of welding cracking. It is suitable for welding base metals such as 6N01, 6082, 6005A and 5083.This welding material features attractive weld formation, excellent weld performance, stable welding arc and minimal spatter. It is applicable for welding components in fields including shipbuilding, locomotive carriages, automobiles, trailers, containers and aluminum alloy structures.
Precautions
1.Adopt open-arc automatic welding, TIG welding or high-power plasma welding. Use 100% argon (Ar) as the shielding gas.
2.Ensure a well-shielded welding site with wind protection measures to prevent the dissipation of shielding gas, which may induce welding defects.
3.Thoroughly remove oil stains, oxide films and other contaminants from the welding area prior to welding.
