This is the process where you use direct electrical heating on the ends of the pieces to be welded and then forge them together. This type of welding process comes under the category of resistance welding and this process is commonly known as FLASH BUTT WELDING.By this process material are joined axially.the two workpieces to be joined are placed end to end on a same axis . a small gap is maintained between the workpiece and a very high current(100000A) is passed through the workpiece. once the gap between the two material reaches a critical value the air present between workpiece ionizes with a FLASH. this flash removes the oxide layer ( due to this oxide layer its difficult to weld) from the material surface and also makes the material little soft near the ends. Once the material becomes sufficiently soft AXIAL PRESSURE is increased to make a joint.

This process is used to weld sometimes railway tracks(Delhi metro track),automobile axle,joining blades of a band saw etc.

VOLTAGE <10volts , CURRENT = 100000amp , POWER = 200kva

Which is better tig welding or plasma welding?

The art of welding has many shapes and forms. There is gas welding, stick welding, tig welding and mig welding. Each has its atvantages in working with various materials. It depends upon what you are welding and what you want to accomplish. For instance, welding rusty metal is usually welded with stick welding as the stick penetrates and burns up rust better than other methods. As far as I know, plasma is only for cutting and not welding. Tig welding is better for intricate welds and visual appeal.
