Experimental analysis on the variable polarity plasma arc pressure
variable polarity plasma arc arc pressure orthogonal experiment
2011/8/5
Arc pressure is one of the key factors for variable polarity plasma arc(VPPA) and welding pool formation. In this paper, VPPA pressure was measured by pressure transducer and U-tube barometer methods....

Sensing controlled pulse key-holing condition in plasma arc welding
controlled pulse key-holing efflux plasma voltage keyhole plasma arc welding
2010/3/17
According to the strategy of controlled pulse key-holing, a new sensing and control system was developed for monitoring and controlling the keyhole condition during plasma arc welding (PAW). Through s...
Prognosis of effects of remelting performed by means of plasma arc
Heat Treatment Remelting Arc Plasma Diagnostics
2011/3/11
Selection of remelting parameter is performed mainly by trial and error method, which is time-consuming and expensive. The performed investigations are aimed to create the method for fast prognosis of...
