[0002] Riveting welding is a type of electric welding. The usual welding method is to penetrate the object to be welded with a welding rod. It is generally used to weld relatively thick metals. The riveting welding process is particularly suitable for connecting parts made of different materials (such as plastic and metal). There is a rivet column on one part, which extends into the hole of another part. Then, through the cold flow or melting of the plastic, the rivet column is deformed to form a rivet head, which mechanically locks the two parts together. During the riveting welding process, the workpiece needs to be turned over for processing.
