Xi'an Aluminum Alloy Welding
Tungsten arc welding is widely used in the industry for welding aluminum plates. Its advantages are concentrated heat, stable arc, dense weld metal, and high joint strength and plasticity. The welds are beautifully formed and high-quality welded joints can be obtained.
Welding method Before welding, the oxide film and oil stains on the welding joint on the workpiece and the surface of the welding wire must be strictly removed. During preheating, the workpiece is slowly heated to about 10%. AC power is generally used, and the purity of the argon gas is not less than 1%. In order to prevent cracks at the arc starting and arc closing locations,
sometimes it is necessary to add arc starting and arc extinguishing plates. When the arc burns stably and the tungsten extreme end is heated to a certain temperature, the arc can be introduced into the welding zone. After welding, care should be taken to protect the anti-corrosion aluminum oxide film. Inquiry phone number
