STUDY ON THE PRESSURE IN PLASMA ARC*
Abstract:
The axial pressure in plasma arc is measured under different conditions. The effects of the parameters, such as welding current, plasma gas flow rate, electrode setback and arc length, on the pressure in plasma arc are investigated and quantitative analyzed to explain the relationship between the quality of weld and the matching of parameters in plasma arc welding process.
Key words: Plasma arc Pressure Quality |
