High-productivity
PTA torch for deposition of composite alloys with
separate feed of base and hardening materials |
|
The PP-6-02 PTA torch is designed mainly for surfacing
of composite alloys with separate feed of base and
hardening materials but it is possible to deposit
general Fe-, Ni- and Co- based alloys.
It consists of two parts - plasma torch and
holder with vertical disposed coupling.
|
The plasma torch is attached to the holder by four screws.
This permits to connect or disconnect it for service very
quickly.
The plasma 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.
