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. Possible to use with DCEP.
Basic coated electrode with Ni-Cr-Fe type nickel base deposit. Used for repairing and joining of nickel alloys, 5 - 9% Nickel steels, cryogenic stainless steels down to -196°C, Incoloy 800 and other high temperature steels. For joining dissimilar materials as stainless steels/low alloyed steels, stainless steels/Nickel alloys, buffering of difficult to weld steels. Weld metal deposit is insensitive to cracks, has very good resistance to acids, salts and alkaline solutions, molten salt (e.g. cyanide) in oxidizing and carburization atmospheres (avoid a sulphurous atmosphere). Generally used for welding on oven parts, burners, heat treatment equipment, cement works, moulds, transport and storage tanks of liquid gas. Chemical industries, petrochemical industries, glassworks, civil engineering, repairing and maintenance workshops.
Heavy coated, high recovery (170%) surfacing and hard surfacing electrode which gives Nickel-Chromium-Molibdenum alloy weld metal. Weld metal is resistant to abrasion, impact, corrosion and high temperatures. Especially used in welding of hot-work press tools which are subjected to above service conditions. Has a stable arc and weld metal is free of cracks and porosity. So, ENI 424 electrode is also suitable for crack-free welding of parts which are subjected to severe thermal stress and chemical attack. Suitable to use in welding hot-work press tools, forge dies, hot-stripping tools, pump rotors, valves. Preferred to use with DC, electrode in positive (+) and possible to use also in AC. Preheating to 400°C - 500°C is required, depending on the size, shape and chemical analysis of the part to be welded. Welding shall be performed with short stick-out distance, perpendicular to base metal and craters shall be filled well.
Electrode having a pure nickel core wire and producing Inconel type weld metal which is crack-proof and high resistant against heavy impact at low temperatures. Suitable for fabrication of storage and transportation tanks of liquidified gases such as nitrogen, oxygen, argon, methane, ethylene. Also suitable for construction of reactors. Excellent results can be obtained in difficult to weld steels with low weldability. Very high durability to corrosive media at temperatures from - 250°C to 1200°C.
