Resistance or Friction welding are two welding methods that fit into a group of processes that functions with a work piece that is moving and another piece that remains stationary. In the process heat is generated through friction as the two pieces comes mutually and an upset (a side force) displaces and fuses these materials.

Friction welding is normally used with thermoplastics and with additional metals and is used a lot in the aviation and automotive industries. In friction welding there is no melting and the heat is bound for to the weld border. These generate a small heat zone. Also, as the friction is happening it cleans the exterior of the materials to be welded so the welder does not have to arrange the surfaces before welding.
