Aluminium strip 7075 in the air and welding easily oxidized, the formation of alumina (Al2O3) high melting point, very stable, easy to remove.
Before aluminium strip 7075 welding, use a chemical or mechanical method to carry out strict surface cleaning, remove the surface oxide film. TIG welding, the use of AC power, through the "cathodic cleaning" role, remove the oxide film. Gas welding, the use of solder to remove the oxide film. In the thick plate welding, can increase the heat of welding, for example, helium arc heat, the use of helium or argon-helium mixed gas protection, or the use of large-scale melting gas protection welding, in the case of direct current, do not need "cathode Clean up ".
Aluminium strip 7075 and the linear expansion coefficient of aluminium alloy 7075 is about twice the carbon steel and low alloy steel.
