Carbide Hard Facing

MIG welding robot

Our carbide hardfaced wear parts are manufactured with two different welding processes:

1. Tungsten Carbide chip hard facing
2. PTA welding process

With these two manufacturing processes we are able to offer a wide range of wear protection to our customers.

We also offer individual hard facing solutions. Do not hesitate to contact us if you have a question about carbide hardfaced wear parts . We will be glad to find a hard facing solution for your application.




tungsten carbide


1. Tungsten Carbide chip hard facing

Tungsten carbide chip hard facing uses the MIG (metal inert gas) welding process.

MIG welding is the process of using electricity to melt and join pieces of metal. In the MIG welding process, the welding torch is used to make a small molten pool on the substrate.

We supplement  this welding process by adding tungsten carbide. We introduce tungsten carbide chips into the molten matrix on the tooth to increase its wear resistance and durability.

example of use

Features of Tungsten Carbide chip hard facing

• very aggressive, highly wear resistant hard faced surfaces
• teeth are very resistant to contaminated material

PTA welding process

2. PTA welding process

The PTA (Plasma Transferred Arc) process deposits a metallic material in powder form to the substrate, which produces a metallurgically bonded,  hard, wear-resistant coating.
Our tungsten carbide powder coating allows us to  manufacture highly corrosion and wear resistant components.

example of use

Features of PTA hard facing

• wide range of overlay alloys
• coatings are corrosion resistant
• automated process
• very thin build up is possible
• coatings are quickly applied
• smooth surface
• multilayer welding possible
