Friction welding is a solid-state welding process that generates heat through mechanical friction between workpieces in relative motion to one another with the addition of a lateral force called upset to plastically displace and fuse the materials. Because no melting occurs friction welding is not a fusion welding process but a solid-state welding technique more like forge welding. This technique allows for closer weld spacings on thicker materials than are possible with the conventional approach.
This is a list of welding processes separated into their respective categories.
Numbers in parentheses are obsolete and were removed from the current 1998 version of ISO 4063. Projection welding has fewer variables that affect the resistance welding process as compared to spot welding. When the welding control applies voltage to this valve. The Solenoid Valve is an electrically operated air valve in the compressed air line connected to the air cylinder on the welding machine.
