Which of the following is a type of fusion welding?

Explanation:

Welding:

It 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

i. Fusion welding

ii. 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, Carbon arc welding

In solid-state welding, 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
