Drill string hardfacings are composites of steel and tungsten carbide applied by welding techniques. This paper discusses the welding process and the important metallurgical variables involved. The importance of proper tungsten carbide selection is emphasized. Experimental results are presented for casing wear by hardfacings and for hardfacing abrasive wear resistance. Guidelines are given for hardfacing selection based on these test results and field experience.
