The INCONEL 112 welding rod is a nickel-chromium-molybdenum flux-coated consumable classified as ENiCrMo-3 under AWS A5.11 / ASME SFA 5.11 (UNS W86112, Werkstoff Nr. 2.4621, ISO ENi6625, ASME IX F-43). In SMAW practice, welders refer to this as an Alloy 112 stick electrode for manual arc welding. This filler electrode excels at overlay cladding, dissimilar metal welding and direct joining of Ni-Cr-Mo base metals across a service range from cryogenic (-196°C / -320°F) up to 982°C (1800°F).

ENiCrMo-3 is compatible with Inconel 625, Incoloy 825, 25-6MO and other Mo-bearing stainless steels. The weld deposit delivers 760 MPa (110 ksi) minimum tensile strength and 30% elongation with excellent resistance to pitting, crevice corrosion and chloride stress-corrosion cracking. Standard electrode diameters range from 2.4 mm (3/32 in) to 4.7 mm (3/16 in), all operated on DCEP polarity. Most industries include oil and gas, chemical processing, marine, nuclear, power generation, offshore and cryogenic service. Three primary uses drive selection: dissimilar metal welding, overlay cladding and welding of Ni-Cr-Mo base metals.

Industrial Applications of INCONEL 112 (ENiCrMo-3) Welding Electrode

Exceptional pitting resistance and dissimilar metal weldability make the ENiCrMo-3 welding electrode a preferred consumable for these SMAW applications:

Dissimilar Metal Joining: Welding nickel alloys (Inconel 625, 718, Incoloy 825) to stainless steels, carbon steels and low-alloy steels. The ~60% nickel content provides metallurgical compatibility at the fusion zone.
Overlay Cladding: Corrosion-resistant weld overlay on carbon and stainless steel substrates for chemical processing vessels, heat exchangers and reactor internals.
Cryogenic Service: LNG tanks, cryogenic piping and 9% nickel steel structures operating down to -320°F (-196°C). ENiCrMo-3 maintains excellent Charpy V-notch toughness at cryogenic temperatures.
Nuclear Industry: Pressure vessel superheaters, steam separators and tube plates per ASME code. Qualified under ASME Section IX with F-43 grouping.
Chemical and petrochemical: reactor vessels, heat exchangers and pipes in process environments that contain hydrochloric acid, sulfuric acid and chloride.
Offshore and marine: parts that are exposed to seawater, equipment on offshore platforms and piping that is below the surface. Resists pitting and crevice corrosion in marine environments with a lot of chloride.
Power Generation: Parts of the boiler, pipes for the FGD system and exhaust systems for the turbine that work in high-temperature oxidising and reducing conditions.
Maintenance and Repair: Using portable SMAW to fix corroded or broken nickel alloy equipment in the field. All-position capability makes it ideal for field welding.

These ENiCrMo-3 welding electrodes operate reliably from cryogenic (-196°C) up to 1800°F (982°C). On the shop floor, welders commonly call this the ‘112 rod’ or ‘625 stick electrode’.

Storage & Handling of ENiCrMo-3 Coated Electrodes

ENiCrMo-3 coated electrodes use a mineral-based flux coating sensitive to moisture. Improper storage causes porosity and hydrogen-induced cracking.

Store sealed canisters at 10-32°C (50-90°F) with humidity below 50%. After opening, transfer electrodes to a holding oven at 250-400°F (121-204°C). Issue only one shift’s quantity. Limit atmospheric exposure to 4 hours maximum before reconditioning.

Recondition exposed electrodes at 600-700°F (316-371°C) for 2-3 hours. Preheat cold electrodes at 200-250°F first. Do not recondition more than 3 times. Moisture in the flux releases hydrogen into the weld pool, causing subsurface porosity in nickel alloy welds.
