how will you classify tha gas welding
Answers
Welding processes can be classified based on following criteria;
Welding with or without filler material.
Source of energy of welding.
Arc and Non-arc welding.
Fusion and Pressure welding.
Welding can be carried out with or without the application of filler material. Earlier only gas welding was the fusion process in which joining could be achieved with or without filler material. When welding was done without filler material it was called ‘autogenous welding'. However, with the development of TIG, electron beam and other welding processes such classification created confusion as many processes shall be falling in both the categories.
Various sources of energies are used such as chemical, electrical, light, sound, mechanical energies, but except for chemical energy all other forms of energies are generated from electrical energy for welding. So this criterion does not justify proper classification.
welding and its classification. 4:54 PM , Posted in Welding and Its Classification. Welding: Welding is a process of joining two metal pieces by the application of heat. Welding is the least expensive process and widely used now a days in fabrication.
