Classification of welding Based on Mode of Energy Transfer
Energy is converted from one form to another. Any form of energy can be converted to heat energy, which can be used for welding.
1. Electrical energy converted to heat energy - Arc, Resistance welding.
2. Mechanical energy to heat - Friction welding.
3. Chemical energy to heat - Gas welding, Explosive welding.
4. Light energy to heat - LASER welding.
5. Sound energy to heat - Ultrasonic Welding.
