PTA torch with accessory nozzles for outside surfacing |
PP-8 PTA torch is designed for PTA-process
for wide range of applications.
It consists of two parts - PTA torch and
holder with vertical disposed coupling.
The PTA torch complete set includes two couples of
plasma and focusing nozzles of different dimensions.
Indeed, there are three torches in one. Necessary combination
of nozzles is selected according to required power and concentration
of plasma arc (see Table I.).
It is possible to deposit Fe-, Ni- and Co- based alloys
on working faces of different parts to protect them against
wear, corrosion etc. Pure argon (99,995% Ar) is used as
a working gas.
