Plasma welding is very similar to TIG as the arc is formed between a pointed tungsten electrode and the workpiece. However, by positioning the electrode within the body of the torch, the plasma arc can be separated from the shielding gas envelope. Plasma is then forced through a fine-bore copper nozzle which constricts the arc. Three operating modes can be produced by varying bore diameter and plasma gas flow rate: 1. Microplasma: 0…See more on twi-global.comsp.info Plasmaswelds. The intense heat created by the plasma produces a pressure within the plasma that is high enough to counteract the pressure produced by over 300 feet of water, allowing arc welding to be performed deep under water for offshore oil rigs or ship repair.

The difference is that in plasma welding, the arc is sharply constricted by a cooled gas nozzle through which a flow of plasma gas is directed. The shielding gas flows through the outside gas nozzle, providing an optimum gas shield to the weld seam. The result is a concentrated arc with maximum energy ...sp.info Advantages of plasma welding: Often-overlooked PAW …PAW is an arc welding process that uses a nonconsumable tungsten or tungsten alloy electrode, much like GTAW. The primary difference between these two welding processes is that in PAW, the electrode is recessed in a nozzle that serves to constrict the arc. Plasma gas is ionized in the constricting nozzle and exits the nozzle at high speed.
