i think roorkee will be batter option
metal inert gas (MIG) welding
Welding machine companies are important, because welding machine manufacturers like Artech Welders, Dynarc Systems, Crystal Electrodynamix are provides all types of welding machines for various business firms.
There is a tremendous importance of welding in engineering, there are even such things as welding engineers ( I am one). Welding is what holds the majority of structures together--bridges, cars, tractors, cranes, buildings, etc...If any engineer does not have a good understand of this very popular joining process major problems can exist, such as failures from designing a joint that is un-weldable. Most companies these days are trying to hire welding engineers to help with these problems. Welding can get very specialized with more technical metals and applications.
