Plasma Powder Feed Welding Products

Restore Cracked and 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.

Plasma Powder Feed Welding is Perfect for Parts Such as:
Turbine blades
Dies
Pumps
Valves
Screws
Shafts
Rotors
Hammers
Sleeves
Cams
Gears
Bushings
Any part requiring restoration of worn metal surfaces back to dimension
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
Metallurgical bonded overlays with minimal dilution of the base metal
Wide range of alloy powder filler materials (wire materials are limited)
Powder is easier to apply than wire welding
Equipment can be used for manual or automated welding
