Ans. There are several types of welding techniques, including:
- Arc welding: This involves using an electric arc between an electrode and the base material to create a weld.
- Gas welding: This method uses a flame produced by burning a fuel gas, such as acetylene, to melt and join metals.
- TIG welding: Tungsten Inert Gas (TIG) welding uses a non-consumable tungsten electrode to produce the weld.
- MIG welding: Metal Inert Gas (MIG) welding uses a consumable wire electrode and a shielding gas to protect the weld from atmospheric contamination.
- Resistance welding: This technique uses the heat generated by passing current through the materials to be welded.
