Nickel-based welding electrodes are designed for welding corrosion-resistant nickel alloys of the Alloy 625 series (UNS N06625, W.Nr. 2.4856), such as Inconel 625, Nicrofer 6020hMo, and similar alloys, operating at extremely low temperatures down to 980°C.
These electrodes have significantly lower iron, sulfur, and phosphorus content compared to ISO and AWS standards. The welded metal exhibits high resistance to application-induced corrosion, intergranular corrosion, pitting corrosion, and crevice corrosion, and can be used for welding parts subject to wet corrosion at temperatures up to 600°C, carbonization and oxidative corrosion at temperatures up to 1000°C, and sediment saturation.
Welding electrodes are used in the manufacture of equipment that comes into contact with inorganic acids such as nitric acid, sulfuric acid, hydrochloric acid, phosphoric acid, various organic acids, alkalis, high-temperature seawater, environments with high chloride ion content, halogens, and hydrogen chloride gas.
These welding rods can also be used to weld nickel alloys such as XNH70Y, XNH78T, 800 and 825 alloys and similar types, corrosion-resistant super austenitic steels with molybdenum content up to 6% such as 0X23N28M3D3T, 254 SMO (e.g., UNS S31254) and similar types, iron-nickel alloys such as XNH32T, X10NiCrAlTi 32 20 (1.4876) and similar types, with limited weldability, as well as to create surface transition layers and anti-corrosion coatings on products made from high-strength and high-strength steels with low carbon and reasonably diamond content.
