In order to make the pure aluminum alloy ship have a longer service life, the following requirements should be mastered when welding it:

1. Use mechanical or chemical methods to remove oxides on the groove and surrounding parts of the workpiece and the surface of the welding wire before welding.

2. Use qualified shielding gas for protection during welding.

3. In the gas welding, flux is used, and the oxide film on the surface of the molten pool is constantly picked up by the welding wire during the welding process.
