Low heat input basic coated type high-yield hydrogen controlled electrode.
LoTherme 351 is ideally suited for welding carbon steels used in the construction of machinery and equipment subjected to heavy dynamic load, impact and severe service conditions. Some of the typical applications include: Heavy structures subjected to dynamic loading and impact, Highly restrained joints, Rail coaches, Wagons, Ships, Girders for columns, bridges, Blast furnace shells, Rotary kiln shells, building machinery, Earth moving machinery, Boilers, Pressure vessels.
ULTIMATE TENSILE STRENGTH : 53 kgf/mm2
ELONGATION (L=4d) : 28 %
Redry the electrodes at 250°C for one hour before use. Clean the weld area completely free of oil, grease, paint, rust or any other foreign matter. For welding heavy sections in cast steel, preheating of the part may prove beneficial. Use short arc.
