Which of the following welding is NOT a fusion welding process?

Which of the following welding is NOT a fusion welding process? Correct Answer Friction welding

Explanation:

Welding:

  • 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

Fusion 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.

Solid-state welding:

  • In solid-state welding, the joining of materials is performed with the help of heat and pressure or pressure alone.
  • Types: Forge welding, Ultrasonic welding, Explosive welding, Friction welding,
