Types of Welding

Welding is a process of joining two metal pieces by the application of heat.

Welding is the least expensive process and widely used allover the world now a days in fabrication.

Welding joints different metals, in which heat is supplied either electrically or by mean of a gas torch.

Different welding processes are used in the manufacturing of Auto mobiles bodies, structural work, tanks, and general machine repair work.

In the industries , welding is used in refineries and pipe line fabrication. It may be called a secondary manufacturing process.
