Description: Ni307-3 is a nickel-based electrode with low-hydrogen sodium coating. Use DCEP (direct current electrode positive). It has good crack resistance because the weld contains a certain amount of manganese, niobium, and other alloying elements. Application: It is used for the welding of nickel-chromium-iron alloys (such as UNS N06600) and the surfacing of steel. The working temperature is generally not higher than 480 ° C, and the crack resistance is good. Suitable for atomic furnace pressure vessel and chemical tank welding.
