Design, Manufacturing and Testing of Multiuser Three Phase Welding Machine

Welding is a fabrication or sculptural process that joins materials, usually metals or thermoplastics, by causing fusion, which is distinct from lower temperature metal-joining techniques such as brazing and soldering, which do not melt the base metal. In addition to melting the base metal, a filler material is often added to the joint to form a pool of molten material (the weld pool) that cools to form a joint that can be as strong, or even stronger, than the base material. Pressure may also be used in conjunction with heat, or by itself, to produce a weld. All the welding machines are 1phase and 2phase in nature and only one user can work on one machine, no other one user can work on same machine. If we use another holder for welding then we should use another welding machine, so it will increase cost of machine, it takes some space, energy use, so, by using three phase welding machine we can overcome this problem. In three phase welding machine we use three holders at a time for low and medium work and for heavy work we can use two holders at a time.
