Hardfacing with the arc welding process is a low cost method of depositing wear resistant surfaces on metal components to extend service life. Although one uses hardfacing primarily to restore worn parts to usable condition, it benefits new components. In addition to extending the life of new and worn components, hardfacing lessens the need for replacement parts, increases the operation efficiency by reducing both downtime and overall costs, and allows for the use of a less expensive base metal. Restoring worn parts frequently involves rebuilding worn areas close to working size using tough, crack-resistant welding materials which one can deposit in an unlimited number of layers. Or, it involves hardfacing, usually limited to one, two or three layers. The author discusses how to choose the welding material, apply weld deposits, select materials, and avoid spalding, underbead, cracking, stress failure, and cross cracking when hardfacing.
