Description

Technical Field

[0001] This utility model relates to the field of metal processing technology, specifically to a spot welding device for welding aluminum plates to aluminum plates. Background Technology

[0002] Aluminum sheet is a type of aluminum material. It refers to aluminum products made by plastic processing methods such as rolling, extrusion, stretching and forging of aluminum billets. In order to ensure the final performance of the sheet, the finished product is subjected to annealing, solution treatment, quenching, natural aging and artificial aging treatment. In order to process or extend the aluminum sheet, it is necessary to weld two aluminum sheets together. Aluminum sheets are usually welded using spot welding. Existing aluminum sheet welding requires manual alignment of the two aluminum sheets. During the welding process, the aluminum sheets are easily pushed and over-displaced, which affects the welding quality of the aluminum sheets. In order to address the above problems, this application designs a spot welding device for welding aluminum sheets to aluminum sheets. Utility Model Content
