Apollo-Clad provides powder welding services for hardfacing brazing services. Powder welding, commonly referred to as spray and fuse or high temperature brazing, provides a quick, low cost repair option for previously hardfaced surfaces. When applied to new parts such as stabilizer blades, tungsten carbide tiles combined with sprayed spherical fused tungsten carbide can provide an excellent wear resistant coating for the most challenging formations.
Build Up and Repair
Build up and repair can also be performed with large angular crushed tungsten carbide in a brass matrix (clusterite, kutrite, itcoloy, composite rod). This process is commonly applied to downhole drilling tools for milling tools, fishing tools, and reaming tools. Brazed tungsten carbide and/or polycrystalline diamond compacts (PDC’s) can be added when needed for enhanced cutting and reaming action.
