Joining

Joining

Welding is one of the manufacturing processes where two or more materials can be joined permanently through coalescence formation with or without the application of external heat, pressure, or filler metal. Welding processes can be broadly classified as fusion welding and solid state welding. In fusion welding processes, significant amount of heat (thermal energy) is applied from external source in order to fuse (melt) the faying surfaces of the components

Thermal plasma is the ionic form of matter that is obtained by heating suitable gas to a very high temperature. Plasma consists of excited ions of gaseous atoms and free electrons (thus plasma can conduct electricity). Localized temperature of plasma can reach 30,000°C or even more. Such a high temperature can virtually melt and vaporize any material regardless of its physical state. An artificially created controllable jet of high temperature
