1. Causes
1) Insufficient gas purity.
The surface of the aluminum substrate is not clean.
3) The selected welding wire quality is subpar, evident in the high amount of impurities in the wire smelting and poor control over the surface oxidation film treatment. Consider using Zhengzhou Ship King brand TIG aluminum welding wire.

Preventive Measures

Check for any leaks in the air supply hose, ensure proper ventilation, verify that the gas nozzle is securely fastened, and confirm the correct use of the protective gas.
(2) Use the proper storage method or contact Ship King Welding Materials.
3) Prior to using other mechanical cleaning methods, first remove all oils and greases.
4) To ensure exceptional welding quality, it is recommended to use a specialized stainless steel brush for surface oxide film removal. Generally, during welding, due to efficiency considerations, the cleaning of the oxide film is not given special attention.
Always select the appropriate welding wire during the welding process. Different aluminum plates require welding wires with matching compressive and tensile strength.
