AWS A5.13 ENiCrFe-1 Nickel alloys Manual electrode Welding accessories
Nickel-based alloy welding wire has good performance of resistance to active gas, caustic medium, corrosion resistance to reducing acid medium, and has high strength, good plasticity, cold and hot deformation and processing and welding characteristics, therefore, widely used in petrochemical, metallurgy, atomic energy, marine development, aviation, aerospace and other industries, to solve the general stainless steel and other metals, non-metallic materials can not solve the engineering corrosion problem, is a very important corrosion-resistant metal material. Nickel-based alloys refer to alloys that are nickel-based and contain alloying elements and can resist corrosion in some media. When classified by its chemical composition, there are mainly nickel, nickel-copper alloys, nickel-molybdenum (nickel-molybdenum ferrolybdenum) alloys, nickel-chromium (nickel-chromium-iron) alloys, nickel-chromium-molybdenum (including nickel-chromium-molybdenum alloys and nickel-chromium-molybdenum copper alloys) and nickel-iron chromium (both iron-nickel-based alloys) and other categories. Pure nickel welding wire ERNi-1 is used to weld 200, 201 nickel alloy and nickel-plated steel plate; welding of steel and nickel dissimilar materials; Surface overlay welding of steel. Nickel-copper welding wire ERNiCu-7 Monel 400 alloy itself welding; and the welding of Monel 400 alloy with steel; Used for surfacing of steel. Nichrome welding wire ERNiCrFe-3 is used for welding dissimilar material welding of creep-resistant joints; – Welding of austenitic, ferritic steels and high nickel alloys, welding of alloy steels containing 9% nickel Nichrome welding wire ERNiCrFe-7 is used for welding alloys and surfacing welding of steel, especially suitable for the construction of nuclear reactors. Welding of nickel-chromium-molybdenum welding wire ERNiCrMo-3 INCONEL625, INCONEL825, INCONEL25-6Mo and MONEL400 alloys; – Welding between ultra-high strength austenitic steel and INCOLOY020 alloy; Welding between nickel-based alloys and stainless steel dissimilar materials; Hardfacing of steel
Application & Standard
This COBALT-BASED SURFACING ELECTRODE CAN BE USED FOR LINING SLEEVE OF SHAFT SLEEVE, CUTTING EDGE OF CHEMICAL FIBER EQUIPMENT, SAWTOOTH, SCREW PUSH ROD, HIGH temperature and HIGH pressure VALVE AND HIGH pressure pump ETC. The surface roughness of the workpiece should be less than Ra12.5μm, and the surface rust, oil and other dirt should be strictly removed. The matrix should not have cracks, pores, sand and other defects, and the edges and corners should be rounded. Before surfacing, different temperatures should be selected according to the substrate material for preheating. When the matrix material is pearlitic heat-resistant steel or martensitic stainless steel and other materials with poor welding performance, the austenitic stainless steel surfacing layer should be welded on the matrix surface, and then the cobalt-based alloy should be surfacing after smooth processing to improve the crack resistance and avoid cracks. Either AC or DC arc welding power supply can be used for D802 and D812 electrodes. Dc arc welding power supply is recommended.
Features
GEH-SL12 titanium calcium coated cobalt-base surfacing electrode. Cobalt-cr-tungsten alloy is used as the core wire. Dc reverse connection is recommended. Surfacing metal can maintain good wear resistance and corrosion resistance at 650℃. Before welding, it must be baked at 300-350℃ for 1 hour; The hardening layer on the base metal surface should be removed to avoid cracks and brittleness. According to the size of the base metal workpiece and the type of base metal, it must be preheated at 300-600℃, and small current short arc welding is appropriate.
