Reduced iron powder shall be applied to the electrode

Iron powder electrode is to improve the electrode deposition efficiency, in the coating to add a certain amount of electrode with reduced iron powder deposition efficiency of more than 105% of the electrode, which is characterized by iron powder thermal oxidation produces a lot of heat, in addition to the arc heating source, so as to improve the operation of the electrode process performance, improve the deposition efficiency When the amount of iron powder is below 30%, adding iron powder is mainly to improve the welding process. If the amount of E5018 iron powder is greater than 30%, and the thickness of the coating is appropriately increased, the welding efficiency of the electrode can be greatly improved. The latter is usually called high efficiency iron powder electrode, and the welding efficiency can reach 160%, the highest can reach 250% Iron powder electrode generally has good process performance, mainly used for flat welding and fillet welding
 
Sulphur is a kind of harmful impurity, with the increase of sulfur content in the electrode, will increase the weld thermal crack tendency, so the content of sulfur in the welding core shall not be more than 0. 04% in the welding of important structures, sulfur content shall not be more than 0. 03%; The electrode produced by our factory uses reduced iron powder, which has been desulfurized for many times in the production process, and the sulfur content of the product is 0.015%
