PTA surfacing the screw blade in centrifugal machine

This set of PTA welding automatic system for spiral conveyer should be installed in the environment of being not the industrial gas of exploding, erosion, vapour, salt mist and so on, and far away from the place of violent shaking and jolting.

The applicable powders for this set of PTA welding automatic system are iron base, Nickel base, tungsten carbide ans so on. The particle size arrange is between 100-300 mesh.

The power supply is the high integrated plasma power welder and the argon is considered as the heat source of plasma arc. The alloy powder as the filled material to surfacing that meet the demand of surface additive of the work piece. Compared with the customary argon arc welding to overlaying, the advantage of PTA powder cladding as follow,: good formation, controllable pool depth, high bonding degree, compact density, it is easy to applied in the automatic system.

Here are two types of arc generate devices for plasma transferred arc and plasma untransferred arc respectively.
The negative of both of them are connecting side by side to connect tungsten electrode in the torch by cables. The positive pole of plasma transferred arc connects to the work piece by cable and the positive pole of plasma untransferred arc connects to the nozzle of torch by cable.
