For example, 1060 aluminum plate, 5052 aluminum plate, and 6061 aluminum plate all have good weldability and good processability. So what should we pay attention to when welding?
1. Selection of welding wire for aluminum plate welding
When welding pure aluminum plates (1060 aluminum plates), the purity of the welding wire is generally not lower than that of the base material;
When welding aluminum alloy plates, the chemical composition of the welding wire generally corresponds to or is similar to the base material;
When welding aluminum alloy plates, the content of corrosion-resistant elements (magnesium, manganese, silicon, etc.) in the welding wire is generally not lower than that of the base material;
2. Selection of aluminum plate welding methods
When welding aluminum sheets and castings that require poor quality repair welding, gas welding is generally used.
Electrode arc welding can be used for repair welding of aluminum alloy castings.
The inert gas shielded welding (TIG or MIG) method is the most widely used welding method for aluminum and aluminum alloys.
Pure aluminum and aluminum alloy sheets can be welded by tungsten electrode alternating current argon arc welding or tungsten electrode pulse argon arc welding.
Pure aluminum and aluminum alloy thick plates can be processed by tungsten helium arc welding, argon-helium mixed tungsten arc welding, gas metal arc welding, and pulse metal arc welding. Gas metal arc welding and pulse gas metal arc welding are increasingly used (argon or argon/helium mixture)
During welding, corresponding pre-welding cleaning and post-welding cleaning are also indispensable. As long as the welding method is correct, good aluminum plates will not desolder or crack after welding.
