Spot Welding Of Aluminum Tube Areas In Need Of Attention

Aluminum pipe conductivity and high thermal conductivity for high current and must be used for a short time, aluminum tube to do that has enough heat to form the core; and reducing surface overheating, to avoid electrode adhesive electrode copper ions to Aluminum clad proliferation, reduce the corrosion resistance of joints. Aluminum tube surface must clean up before welding the oxide film, otherwise easily lead to splashes and the core forming bad , so that solder joint strength
