PTA Powder Surfacing system
The technology features of PTA powder Surfacing:
PTA welding is kind of high efficient welding method which uses the plasma that generated by the gas in the compressed arc area as its heat source and alloy powders as its filler. Compared with other normal heat sources, plasma arc has the advantages of high temperature, concentrated energy, stable arc combustion, small welding heat influence area, quick welding speed, high production efficient and easy to get thin surfacing layer with low dilution rate. It was also easier to realize mechanization and Automation for the welding process. Besides, by using PTA powder welding, fine microstructure and good welding appearance, glossy and smooth welding layer can be got. Only need little machining or even no machining need to be applied after welding. The welding alloy layer and the base work piece were found with good metallurgical blending. It is with strong blending strength and suit to weld on the work piece that with low melting point. As a result, PTA powder welding system is currently the most popular plasma welding method.
The materials applicable to PTA powder surfacing:
Cobalt based powder
Nickel based Powder
Iron based powder
