Specially formulated to avoid harmful phase formation in the dilution zone, even when the base metal is an alloy steel, stainless steel, nickel or copper-based alloy. Exceptionally crack resistant welds due to superior ductility combined with a thermal expansion coefficient closely matching carbon steels. The tough weld microstructure is resistant to prolonged high temperature service and thermal cycling fatigue stresses. EnDOtec®’s annular cross sectional design, automatically produces a higher current density in the electrode’s metallic peripheral sheath. This ensures faster electrode fusion without sacrificing weld quality giving record weld deposition rates over Manual Metal Arc. EnDOtec®’s peripheric cool arc concept produces a low heat imput transfer, which means that welds have better bonding, lower dilution, superior microstructure properties and minimal heat affected zones for maximum service performance.
