Abstract
A hard facing is preferably accomplished with laser clad beads applied to horizontal directional drilling (HDD) component(s). These components may be subject to recirculating fluid regions associated to stepped geometries along a drill string, including various drill string coupling members. For example, laser cladding can be applied to a step region of the sonar housing and starter rod. A method applies a hard face coating such as laser cladding or other suitable hard facing in areas of tight geometric tolerances.
