AI Technical Summary

Technical Problem

The existing electrodes used for resistance welding are prone to displacement during butt welding, resulting in poor neutrality, workpiece extrusion and fracture and scrap, and the losses are large, and the production requirements cannot be met.

Method used

An electrode consisting of two sets of T-shaped electrode blocks is designed. The lower end of the vertical rod of each set of electrode blocks is provided with a groove to accommodate the busbar to be welded, and the two ends of the cross rod are provided with fixed blocks of L-shaped structure. The inner wall of the fixed block cooperates with the outer wall of the cross rod of the electrode block to ensure the stable installation of the electrode block.

Benefits of technology

Through this design, the positioning of the electrode and the base is accurate, which reduces displacement risk, improves neutrality, enhances the stability and success rate of welding, and reduces raw material waste and production losses.
