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 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.
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.
