Low heat input electrode for crack-free welds on a variety of steels, especially for joining SS to CS.
LoTherme-478 is producing crack free, radiographic quality welds. The weld metal has excellent crack resistance and good toughness. It operates equally well on AC as well as DC (+) in all conventional positions with excellent operating characteristics.
LoTherme-478 is ideal for repair and maintenance welding on a variety of steels, dissimilar joints between carbon, low alloy steels to other steels, stainless steels, etc. It is also suitable for buffer layers before hard surfacing. Ideal for joining and building up number of components in earthmoving and mining, thermal power, cement, sugar, general engineering industries, etc.
Ultimate Tensile Strength : 620 MPa
Elongation (L=4d) : 35 %
Ensure the electrodes are dry. Re-dry the electrode at 250°C for one hour before use. Clean the weld area completely free of oil, grease, paint, rust or any other foreign matter. Use low current, short arc and stringer beads.
