Steel Welding Tungsten Carbide
Weldable tungsten carbide is generally used to mean the joining of tungsten carbide to steel without the use of braze alloy.
In welding tungsten carbide there are two parts. The steel body and the prepared tungsten carbide. The prepared carbide has a surface prepared with something such as cobalt. This pure cobalt surface is fairly magnetically responsive. The steel heats up fastest but the carbide also heats up as well. The difference here is the amount of heat transference from the steel to the carbide. The steel then flows onto and around the tungsten carbide part. The steel alloys with the cobalt on the surface. It forms a very strong bond.
