Improvement of wear resistance of aluminum alloy by plasma transferred arc welding process.
Journal of Japan Institute of Light Metals, 1999 The purpose of this study is to improve the hardness and wear resistance characteristics of the aluminum alloy using Plasma Transferred Arc process, called PTA process. The PTA process has been mainly applied to surface modification to steel products. It has some difficulties to apply this PTA process into aluminum products due to its low melting point

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.
