GEMET – 303 is a hardfacing electrode with an exceptional resistance to abrasion and wear in addition to resistance to mild impact. An all-position electrode giving uniform beads Deposits is hard and tough and free from porosities. Deposits are machinable using carbide tools. Weld deposit is air-hardening.
Crushers, baffle plates, pressure rollers, shear blades, roller, wheel riser, stompers, excavator parts, rock drills, tractor grousers, and paddlers.
Clean surface thoroughly. Use short arc with DC reverse polarity. No more than 2-3 layers should be deposited. e buffer layer of GEMET – 103 on high carbon steel. reheat crack sensitive parent metals to 200-300°C
