It is convenient to use and has a smooth surface. After pouring, there is no need to plaster the wall again, so it is widely used.

[0003] During the preparation of the aluminum alloy formwork, it is necessary to weld each component through the aluminum formwork automatic welding equipment disclosed in the invention patent with the publication number CN107020465B and a kind of aluminum formwork welding system disclosed in the invention patent with the publication number CN107649763B in three dimensions.

[0004] However, it is found in the use process that the existing welding device has a relatively simple structure. When welding the rib plates of special-shaped aluminum alloy formwork (such as arc-shaped aluminum alloy formwork), due to the high coefficient of thermal expansion of aluminum, the arc surface is prone to deformation during the welding process, affecting the welding effect and resulting in poor practicability. Therefore, there is an urgent need for an efficient welding device for special-shaped aluminum alloy formwork to improve the above problems. Summary of the Invention
