Description

Technical Field

[0001] The utility model belongs to the technical field of aluminum alloy template welding, in particular to an auxiliary tooling for welding aluminum alloy building templates. Background Art

[0002] Aluminum alloy formwork is made of aluminum alloy profiles as the main material. It is a formwork suitable for concrete engineering made through machining and welding processes. When processing aluminum alloy building formwork, it is generally necessary to weld the aluminum alloy plates perpendicular to each other to form a regular formwork to facilitate the injection of concrete.

[0003] In the aluminum alloy formwork welding process, during manual welding, it is necessary to manually hold the two plates so that they are at 90 degrees to each other, and then use a welding machine to weld them. The holding method has poor stability, which causes the welding point to be offset, resulting in poor aluminum alloy formwork forming effect. For this reason, we propose an auxiliary tooling for aluminum alloy building formwork welding to solve the above-mentioned problems. Utility Model Content
