The Carbon Steel Electrode for use: carbon steel electrode (deposited metal tensile strength less than or equal to 500MPa namely 50kgf/mm2) applicable to carbon steel and low-strength low alloy steel welding. When you choose electrode, usually based on the chemical composition of steel, mechanical properties, crack resistance requirements must take into account the shape of the welded structure, working conditions, by the force condition and welding equipment performance factors. When necessary, Cast Iron Electrodesto carry out the welding test to determine the process measures, and then determine the choice of electrode. Usually requires plasticity, impact toughness, crack resistance, the choice of low-hydrogen electrodes. Special requirements may use a dedicated electrode selection of iron powder electrode in order to improve the welding efficiency, welding position. Low hydrogen, iron powder type electrode before welding electrodes must be baked at 350 ° C above, as far as possible to do with the drying with the use of the principle of how much baking how much, otherwise it will produce welding defects (such as porosity, slag, cracks, deterioration of process performance, etc.). Cellulose type electrode should be strictly in accordance with the provisions of the Manual baking temperature baking, the temperature is too high will burn the cellulose to the drug skin, damage inherent in the electrode process performance. Using low hydrogen electrodes, the welder should be living in the upwind position, to enhance ventilation, to prevent the hazards of welding fumes on the body. Low hydrogen type electrode baking the number of times as much as possible not more than twice to prevent drug skin to become brittle and fall off.
