Highly versatile arc welding rods with an engineered deposit chemistry that offers superior crack resistance and performance when joining dissimilar steels. -- High chromium, nickel alloy for use with AC or DC reverse polarity in all positions. - Weld deposits of exceptional strength (almost 2X of average rod). -- Tensile Strength 128,000 psi (880 N/mm2) (Work Hardened 90,000 psi / 630 N/mm2) -- Yield Strength 90,000 psi (630 N/mm2) -- Elongation 32% -- Reduction of area 32% -- Hardness Brinell 225 – Weld with: - DC reverse (electrode positive) or AC -- Recommended Amps: Min 60 Max 110 -- Maintains strength and corrosion resistance at high and low temps. - Balanced metallurgical structure produces high crack resistance under toughest welding conditions and service apps. - Good wear resistance, overlays take a high polish, and it’s one of the best materials for welding dissimilar metals. - Welds at very low amperages, reducing distortion, base metal dilution - and its low heat input keeps thermal stresses in joints at a minimum. -- Special flux formula eliminates slag interference in horizontal fillets and produces slag designed to turn to powder – making these electrodes ideal for stud pull applications. -- Recommended Techniques: - Clean weld area to be free of rust, grease, paint, or other materials which can cause weld contamination. - NOT necessary to grind flame cut edges. - Adjust amperage to recommended range for electrode size. - Tilt electrode 15 degrees in the direction of travel. - Maintain a short arc length and use stringer beads. - For rapid filleting, raise amperage slightly and drag weld inclining the electrode 45 degrees in the direction of travel. - Back whip craters and remove slag between passes. - A 90 degree V-joint should be used when joining heavy sections. - Upon cooling, slag can easily be removed by light chipping and brushing. - Use Flat, Horizontal, Vertical Up, and Overhead Positions.
