The plasma spray process uses a DC elecric to generate a stream of hi temperature ionised plasma gas ,which acts as the spraying heat source. The coating materials, in powder form ,is carried in an inert gas stream into the plasma jet where it is heated and propelled towards the substrate. Because o
Pre-ground tungsten electrode
As we all know the tungsten electrode have to be ground an angle before welding so that it will have a better performance during the application ,it is very important for the tungsten electrode during welding .
Why the tungsten electrode have to be grou
The pre-ground or called the sharpened tungsten electrode ,as we all know before the tungsten electrode used in TIG welding,the tungsten electrodes have to be pre-ground ,why do this ?to pre-ground the tungsten electrode so that the tungsten electrode could focus in a very central point, maybe some
Choosing one of the six commonly available tungsten electrodes is a crucial first step in successful gas tungsten arc welding (GTAW). In addition, tip preparation is critical. The electrode choices are pure tungsten, 2% thoriated, 2% ceriated, lanthanated, zirconiated, and rare earth.
Plasma Spray Process：Plasma spray system consists of a Plasma Spray Gun, Power Source, Powder Feeder, Control unit and Heat Exchanger. Plasma is formed inside the specially designed plasma spray gun, by introducing a high intensity electric arc between a cathode (tungsten electrode) and anode (nozzl
