How Welding Tungsten Carbide Cutting Tools

Tungsten carbide cutting tools welding and tool steel, high speed steel cutting tools welding is not the same, this is due to the performance of the big differences between steel and carbide caused. Especially steel and tungsten carbide thermal conductivity and thermal expansion coefficients are not the same, tungsten carbide cutting tools welding, it tends to heating or cooling too fast welding of carbide cutting tools which easily lead to stress too much so that the tungsten carbide insert a crack. The larger sizes tungsten carbide inserts, tungsten carbide blade cracking phenomenon is also the more serious. When welding tungsten carbide tools should satisfy a requirement. One is tungsten carbide weld strength must be sufficient to ensure that the maximum amount of tungsten carbide cutting tools, and furthermore is not allowed to have a crack on the tungsten carbide blade.
