Arc pressure is one of the key factors for variable polarity plasma arc(VPPA) and welding pool formation. In this paper, VPPA pressure is measured by pressure transducer and U-tube barometer methods, and advantages ...
The specific Fe-based alloy for direct metal forming was designed and prepared under multi-layer cladding condition.The powder was designed for getting the better formability,toughness and hardness.The experiment used...
