Plasma
Powder Feed Welding Products
Restore Cracked & Worn Metal Parts
to Their Original Dimensions for Maximum Protection
Now you don’t have
to trash your old metal parts. With Plasma Powder Feed
Welding Products, you can make precise repairs on worn
parts and protect them from future wear. Save money
on downtime and part replacement with PWS solutions.
The Plasma Powder Feed Welding Process
The base metal of a component
is melted using a plasma power supply and a plasma
powder feed torch. During welding a controlled amount
of alloy is carried by Argon into an Argon/Hydrogen
shielded and transferred arc plasma column to apply
a metallurgically bonded, wear resistant coating
to the work piece. Accurate control of powder feed
rate, current input (amperage) and gas flow rates
allow the operator to attain precise deposits of
powder material with minimal base metal.
Applications:
Application requirements such as resistance to
abrasion, galling, impact and chemical or heat corrosion are candidates
for plasma powder feed welding. Most ferrous and non-ferrous metals
can be welded with plasma powder feed welding.

Advantages
of Plasma Arc Powder Feed Welding:
|
•
|
Maintenance
and repairs are done quickly reducing labor and downtime
costs
|
•
|
Restores
worn parts and surfaces to their original dimensions
|
•
|
Welding
amperages as low as 0.5 amps and as high as 200 amps
|
•
|
Stable
concentrated cylindrical arc and consistent arc starting
|
•
|
Slight
variations in torch stand off distance have little effect
on bead or heat concentration with a minimal heat affected
zone
