Why is plasma arc welding concentrated in a nozzle?
The plasma arc welding is concentrated because it is forced through a relatively small orifice or nozzle to increase its pressure, temperature and heat. Because of the above characteristic, the arc will now become very stable, improved in shape and heat transfer rate.See all results for this questionWhich is the best description of plasma welding?In Plasma arc welding (PAW) is an arc welding process, a concentrated plasma arc is produced and directed towards the weld area. The arc is stable and reaches temperatures as high as 33,000°C. A plasma is an ionized very hot gas composed of nearly the same numbers of electrons and ions.See all results for this questionWhat is the difference between GTAW and plasma arc welding?Plasma Arc Welding is essentially an extension of Gas Tungsten Arc Welding (GTAW). Like GTAW, a non-consumable electrode is used in Plasma Arc Welding (PAW). However, a different technique is used to deliver the heat for welding in Plasma Arc Welding (PAW).See all results for this question
