We all know that aluminum alloy material is widely used and sometimes needs to be welded. Among them, 5 series and 6 series aluminum alloy material can be welded, but 2A12 aluminum plate is difficult to be welded. Next, 2A12 aluminum plate manufacturer will introduce to you the welding difficulties of 2A12 aluminum plate.

1. 2A12 aluminum alloy welded joints are severely softened with low strength coefficient, which is a big obstacle to the application of aluminum 2A12.

2. Pores are easy to occur in welding of 2A12 aluminum plate.

3. 2A12 aluminum plate is prone to thermal cracks in welding.

4. 2A12 aluminum plate has large linear expansion coefficient and is prone to welding deformation.

5. 2A12 aluminum plate has oxidation film, so we need to adopt some high-power density welding technology.

6. The thermal conductivity of 2A12 aluminum plate is large, and the heat input is two to four times that of the welded steel at the same welding speed.

The above is the introduction of the difficulties in welding 2A12 aluminum plate. If you need 2A12 aluminum plate, please contact us.
