PTA
mini-torch PTA torch for surfacing in hard-to-reach places of different parts |
PP-21
PP-21-01
The PP-21 PTA torch has a flat design and is purposed
for plasma transferred arc surfacing (the PTA-process) in hard-to-reach places of different parts (fillet of shaft, narrow
chink and etc.).
It is possible to deposit Fe-, Ni-, and Co- based alloys.
To avoid an electrical contact between PP-21 and hard-faced
part its side surfaces are covered by ceramic. |
The PP-21-01 PTA torch is modification of the PP-21.
The difference is in holder.
Pure argon (99,995% Ar) is used as a working gas.
