Background
Rivet welding is a welding method of electric welding. The usual welding method is to infiltrate the objects to be welded with a welding rod. Are commonly used for welding relatively thick metals. The rivet welding process is particularly suitable for joining parts made of different materials (for example plastic and metal). One part has a stake which extends into a hole in the other part. The rivet stem is then deformed by cold flow or melting of the plastic to form a rivet head that mechanically locks the two parts together. The process is fast and economical and has the advantage of no need to consume rivets and screws. By changing the design of the welding head, a plurality of different rivet head designs can be obtained. Typical rivet welding applications recommend 1.6 to 4mm (1/16-5/32 inch) diameter studs.
