TUNGSTEN CARBIDE HARDFACING MATERIAL,
METAL SPRAY POWDERS, TORCHES


DONT REPLACE / HARDFACE


During the process of drilling for oil and gas wells the different components such as drill bits, stabilisers, augers etc. are subject to severe abrasion.

Partlife and efficency is of prime importance since the penetration rate depends more or less on the performance of the tools.

Tungsten carbide (OFW) hardfacing materials such as 780 788 and 790 have proven to give excellent results in prolonging the life time of such tools.

 


STABILIZER COATED WITH ARCWEL 790 G


ADVANTAGES OF USING (OFW) GAS HARDFACING ALLOYS


1) Low temperature deposition with minimal change to base metal
2) No special equipment required therefore little investment cost
3) Optimal wear properties in first layer therefore savings in filler material cost
4) Ideal for small or big jobs in house or on site, easy to apply
5) OFW weld deposits provide greater wear resistance then electric arc overlays.

THERMAL SPRAY AND FUSE -METAL POWDERS AND SPRAY TORCHES



Protect and rebuild screws

 


For repair of glass or
plastic injection molds

 


Hardfacing and repair
of mixers

SPRAYFUSE PROCESS (SF)
A simple to use and cost effective method to protect and repair valuable components against wear and tear.
Atomized powders are applied with a special oxy acetylene torch and fused simultaneously to the surface of the metal part.
Precise and thin overlays can be made by diffusion ensuring a perfect bond below the melting point of the base metal.
Coatings made by this process have only a minimum of dilution and therefore retain the original properties.

ADVANTAGES

  • Can be used on steel, stainless steel and cast iron
  • Used for repairs and hard facing of glass, brick, and plastic molds, cylinder heads, shafts, keyways, screws, mixer blades, stabilizers etc.
  • A variety of powders are available to suit most applications
  • No special training of operator required.
  • Simply connect to ordinary oxygen and acetylene gas
  • Supplied as a kit with different size tips for different flame power and powder flow rates.

POWDERS
The following powders are suitable for application with Spray and Fuse torches such as Arcwel 2010, Eutalloy superjet, Colmonoy
The powders as described below are also supplied in different grades for different coating processes such as.
PTA : Plasma transferred arc welding, CS: Cold spraying, HVOF: High-velocity flame spraying
