Spray and Fuse Tungsten Carbide
Spray and fuse is a continuous brazing process that applies the coating and fuses it to the base material in a single process. This process does not melt the base material and consequently there is no dilution of the overlay alloy. The bond is created by the diffusion of atoms between the overlay alloy and base material resulting in a very dense, hard coating with high bond strength.
Features and Benefits
Low heat input reduces dissolution of WC/WC2 during application
Low heat input results in a cooler weld puddle with less carbide sinking
Low heat input results in no dissolution of the base material
Deposit rates up to 15lbs/hour (6.8kg/hour) and up to 0.25” (6mm) per pass
Low residual stress in the overlay allows for multiple passes without cracking and spalling
Low residual stress makes the overlay very impact resistant
ASME recognized welding process
