The Influence of Anode Inner Contour on Atmospheric DC Plasma Spraying Process

Advances in Materials Science and Engineering, 2017
In thermal plasma spraying process, anode nozzle is one of the most important components of plasma torch. Its inner contour controls the characteristics of plasma arc/jet, determining the motion and heating behaviors of the in-flight particles and hence ...

Heat sink effects in variable polarity plasma arc welding [PDF]

The Space Shuttle External Tank is fabricated by the variable polarity plasma arc (VPPA) welding process. In VPPA welding, a noble gas, usually argon, is directed through an arc to emerge from the torch as a hot plasma jet.
