Which of following is NOT a conventional type of welding process?

Which of following is NOT a conventional type of welding process? Correct Answer Friction welding 

Explanation:

Welding is a process of joining two similar or dissimilar metals by fusion, with or without the application of pressure and with or without the use of filler metals.

The fusion of metal takes place by means of heat.

The heat may be obtained from electric arc, electric resistance, chemical reaction, friction, or radiant energy.

Based on the composition of joints, the joining process may be classified as:

Solid-state welding: It is also called as Autogenous welding

It is classified into:

  • Explosive Friction
  • Ultrasonic welding
  • Diffusion welding
  • Friction welding
  • Forge welding

Liquid state welding: It is also called as Homogeneous welding

It is classified into:

  • Resistance welding
  • Arc welding
  • TIG welding
  • MIG welding
  • PAW welding
  • Gas welding

Solid/Liquid state welding: It is also called as Heterogeneous welding

It is classified into:

  • Brazing
  • Soldering

From the above options, Friction welding is not a conventional type of welding process. The first time it is introduced in the 1924 year.
