Electrode ESAB OK 68.81 VacPac

OK 68.81 is a highly alloyed electrode for joint welding of hard welded dissimilar steel, welding of sliding surfaces, and as a buffer layer for welding of hard welded goods. Characteristics of the weldment are high durability, high impact resistance and high wear resistance. The electrode can withstand dilution and dissolving, provides high strength welds in both high alloy and low alloy steel and joint welding of highly dissimilar steel. The high chromium content provides low coefficient of friction and scaling resistance up to 1150oC. Welding at elevated operating temperatures can in many cases be eliminated except for steel with high carbon equivalent, since preheating around 150-200 ° C should be applied. OK 68.81 deserves the term universal electrode for difficult weldments in both common and unusual steel. Suitable applications are rollers, forging tools, thermoforming tools, plastic punch cushions, etc.
