Welding is a metal joining process in which two or more parts are joined or coalesced at their contacting surfaces by suitable application of heat or/and pressure.
Welding processes can be broadly classified into
- Fusion welding
- Pressure welding/solid-state welding
In fusion-welding processes, heat is applied to melt the base metals. In many fusion welding processes, a filler metal is added to the molten pool during welding to facilitate the process and provide strength to the welded joint.
- Types: Arc welding, Gas welding, Oxyfuel gas welding, electron beam welding, laser welding
In solid-state welding, the joining of materials is performed with the help of heat and pressure or pressure alone.
- Types: Forge welding, Resistance welding processes (spot, seam, projection, flash butt, arc stud welding), Ultrasonic welding, Explosive welding
