Description

Technical Field

[0001] The utility model relates to the technical field of steel structure processing equipment, in particular to an assembly spot welding system for H-shaped steel. Background Art

[0002] Steel structure support frames made of I-beams are widely used in various large-scale construction projects. Steel structure support frames are usually manufactured in the factory in advance and then transported to the construction site for use. In the manufacturing process of steel structure support frames, they are usually welded from small angle steels and I-beams or I-beams.

[0003] For large-scale construction projects such as steel structure support frames of large factories, the overall size is relatively large, and the size of the I-beams or H-shaped steels of the steel structure support frames is also relatively large. In the process of producing I-beams and H-shaped steels, multiple steel plates are assembled and welded. At present, it is usually done manually by spot welding the assembled multiple steel plates to finalize the shape, and then the welds are welded by a welding machine. However, when spot welding is done manually, one of the wing plates is usually welded first, and then the other wing plate is assembled and spot welded after the welding of the wing plate is completed. As a result, the current H-beam assembly welding method is inefficient. In particular, when welding the wing plates, two welders are required to weld from both sides of the web, which has high labor costs. In addition, there are problems such as welding smoke and light pollution during welding that affect the health of welders.
