Welding shall be performed with short stick-out distance, perpendicular to base metal and craters shall be filled well. Preferred to use with DC, electrode in positive (+) and possible to use also in AC.
ENI 425 is a Ni-Cr-Mo alloyed covered electrode that deposits weld metal with a composition of Ni-22Cr-9Mo-3.5Nb. It is specifically designed for welding highly corrosion-resistant Ni-Cr-Mo alloys such as Alloy 625, 825, and similar materials.This electrode demonstrates excellent toughness at cryogenic temperatures as low as -196°C, making it suitable for welding cryogenic nickel alloys, such as X1NiCrMoCuN25-20-7.The weld metal is resistant to oxidation up to 1200°C in sulfur-free atmospheres and can be used at service temperatures up to 500°C in sulfur-containing environments. It offers high resistance to stress corrosion cracking, pitting, and crevice corrosion in environments containing phosphoric acid, organic acids, seawater, and highly polluted conditions.The weld metal is insensitive to cracking and exhibits excellent resistance to thermal shocks. ENI 425 is used for joining dissimilar nickel alloys, welding dissimilar stainless steels, joining low-alloy steels to stainless steels or nickel alloys, and for buffering and cladding applications. It is also ideal for repair welding of these materials.
Ni-Cr-Mo-based basic coated electrode depositing a Ni-Cr-Mo-Nb-W alloy weld metal. It provides high performance for welding 9% Ni steels used in cryogenic applications such as LNG tanks (X8Ni9, ASTM A353, ASTM A553, JIS G3127 SL9N). The weld metal delivers high impact toughness down to -196°C, ensuring reliable performance under cryogenic conditions.In sulfur-free environments, the weld metal is resistant to scaling (oxidation) up to 1200°C, while in sulfur-containing environments it can be used at temperatures up to 500°C. In addition to stress corrosion cracking resistance, it offers excellent resistance to pitting and similar forms of corrosion in phosphoric acid, organic acid, seawater, and highly contaminated environments. It also provides high resistance to cracking and thermal shock.It can be used with AC polarity to prevent or reduce magnetic arc blow. It is suitable for welding different stainless steels, various nickel alloys, or for joining low-alloy steels to stainless steels or nickel alloys. Moreover, it can be safely employed for buffer and cladding passes on steels with low weldability and for repair welding of these alloys.
ENI 429 is a basic-coated electrode developed for joining nickel-based alloys and similar heat-resistant materials, offering high performance at service temperatures up to 1000°C. It is suitable for welding alloys such as 2.4663 (NiCr21Co12Mo), 2.4851 (NiCr23Fe), 1.4876 (X10 NiCrAlTi 32 20), and 1.4859 (GX 10 NiCrNb 32 20). Provides strong resistance to oxidizing and carburizing atmospheres, with scaling resistance up to 1100°C. The weld metal shows excellent resistance to hot cracking and maintains high-temperature strength even without post-weld heat treatment. It produces a stable arc, smooth weld bead, and has easily removable slag for efficient operation. ENI 429 is ideal for high-temperature applications like gas turbines, ethylene plants, chemical reactors, and petrochemical equipment. Preheating should be adjusted according to the base material to minimize residual stress and reduce cracking risk.
Electrode having monel core wire, designed for joining and surfacing welds of Monel-clad steels. Suitable for joining Monel alloys to steel; weld surfacing of steel with corrosion-resistant Monel coating. The weld metal is free of porosity and resistant to many chemicals. Suitable for applications with working temperatures from -196°C to 450°C. Weld groove preparation and cleaning should be done carefully. Generally welding should be done in horizontal position with short stick-out distance without weaving. Due to porosity risk of the weld metal, welding and striking shall be started on end plate. Possible to use with DCEP.
