Nickel-based welding rod for welding of ultralow-temperature container steel

[0023] The chemical composition of the core is as follows: C: 0.02%, Si: 0.20%, Mn: 6.14%, P: 0.001, S: 0.002%, Ni: 14.65, Mo: 5.80%, Nb: 0.98, W: 1.36, Fe: 0.12%, the balance is Ni. The weight percentage content of the powder in the coating is: marble 33%, strontium carbonate 3%, potash feldspar 1%, fluorite 3%, magnesium fluoride 7%, cryolite 15%, rutile 15%, titanium iron 7% , Aluminum iron 4%, magnesium aluminum powder 2%, molybdenum iron 5%, niobium iron 3%, tungsten iron 2%. After mixing the powders of the ingredients in the coating uniformly in proportion, add potassium water glass accounting for 21% of the total mass of the coating, stir and mix uniformly, and then send it to the pressure coater to coat it on the solder core. It is baked at a low temperature of 100°C and a high temperature of 320°C to manufacture the electrode.
