PLASMA WELDING


This is an extension of TIG welding. In plasma welding torch, plasma energy is constricated and ensures its most efficient utilisation for welding cutting and spraying. The tip of the tungsten electrode is located within the torch nozzle while the nozzle has a small opening which constricts the arc. As gas (argon) is fed through the arc, it becomes heated to the plasma temperature range (30000 °F to 60000 ° F). The plasma tail flame issues from the torch nozzle acts as a jet of tremendous velocity. The plasma arc is of two types: transferred arc and  non - transferred arc. In the latter, the arc is formed between the electrode and the orifice inside the torch. The process is used for welding of steels, stainless steels, copper, aluminium, titanium, monel and inconel. Plasma MIG welding is a development of plasma welding process. Plasma process is used for cutting applications very efficiently.

Micro Plasma Welding
This is a modified plasma welding process using DC current range of 0.1 - 10 amps. It is capable of welding
extremely thin sheets and foils in the thickness range of 0.05 - 1.6 mm.
