PP-6-04 High-productive PTA torch for outside surfacing with two powder feeding systems

PP-6-04

PP-6-04 PTA torch is designed for PTA surfacing of outside of different parts.

It is possible to deposit Fe-, Ni- and Co-based alloys on working faces to protect them against wear, corrosion etc.

PP-6-04 PTA torch is multifunctional and it is a modification of the PP-6-02 PTA torch.

Unlike the previous model in the PP-6-04 PTA torch two powder feeding systems are realized:
- annular inner distributed powder feeding system
- 2-ports feeding system

They work as independently as together.

One of systems provides uniformly distributed annular powder feeding by means of plasma nozzle slots. Another system provides the powder feeding through 2 opposite ports in the focusing nozzle. Owing to this it is possible to surface the coarse high-melting powders using annular inner distribution system and thin low-melting powders using 2-ports system. Using 2-ports feeding system in order to decrease the powder losses and to improve the bead formation the additional stabilizing gas flow in the PTA torch is used. This stabilizing gas flow increases the stability of arc burning and provides more favourable trajectories of the powder in the arc.

The PTA torch allows to feed at the same time two types of powder from two powder feeders, which melted in a welding pool will provide the receipt of a new type of alloy.

Very effectively to use this PTA torch for hardfacing the composite alloys using separate feeding of the hardening and matrix materials.

It consists of two parts - PTA torch and a holder with vertical disposed coupling.

The PTA torch is attached to the holder by four screws. This permits to connect or disconnect it for service very quickly.

The PTA torch complete set includes two couples of plasma and focusing nozzles of different dimensions. Necessary combination of nozzles is selected according to required power and concentration of plasma arc (see Table I.).

Pure argon (99,995% Ar) is used as a working gas.
