ESAB Wear-Arc WH Electrode - 5/32" X 14" - 8 lb HS - 259145308

The weld deposit of Wear-Arc WH is high in alloy content, extremely deformation resistant, and has 2-4 times greater wear resistance than work-hardened austenitic manganese steel. WH contains approximately 34% alloy, properly balanced to perform the dual purpose of a work-hardening, wear-resistant buildup alloy, and also a high strength welding alloy. The alloy is austenitic and produces tough, crack-resistant welds. Wear-Arc WH produces a dependable bond to manganese steel. Users of type 308, 309, 310, or 312 stainless steel electrodes for rebuilding and repair of equipment constructed of manganese steel find Wear-Arc WH to be a superior electrode for the job. Deposits of Wear-Arc WH, when subjected to high impact and compressive loads, develop a surface hardness of 48-50 Rockwell C and still retain a tough, resilient, deformation-resistant mass under the work-hardened surface

Procedure

Warning:
Wear-Arc WH electrodes are designed for welding with AC/DCEP (Electrode Positive) in all positions. When welding high-carbon steel, preheat to 300-400°F (149-204°C). Do not preheat manganese steel.
Hold the electrode at an angle of 15° in the direction of travel with as short an arc as possible without allowing the coating to touch the weld pool. Stringer beads are preferable. Weaving should be limited to 2-1/2 times the electrode diameter. Slag should be removed thoroughly between passes.
For vertical welding, the electrode should be held perpendicular to the plate using a very slight oscillation from side to side on the root bead. When welding in the overhead position, hold a short arc with no oscillation of the electrode.
Weld deposits cannot be cut with oxy-acetylene torch or by air carbon-arc cutting.
