Welding Consumable

Introduction

NiWire has been producing nickel based solid welding wires for many years from melting to wire drawing. Product forms include continuous wires precision wound on spools used in the Gas Metal Arc Welding process (GMAW or MIG), and cut length rods embossed with grades at ends for Tungsten Inert Gas welding (TIG).

ERNi-1 is used for welding wrought and cast forms of commercially pure nickel alloy (ASTM B 160, B 161, B 162, and B 163 having UNS number N02200 or N02201) to itself using the GTAW, GMAW, SAW, and PAW processes. The filler metal contains sufficient titanium to control weld-metal porosity with these welding processes.

ERNiCr-3 is used for welding nickel-chromium-iron alloy (ASTM B 163, B 166, B 167, and B 168 having UNS number N06600) to itself, for the clad side of joints in steel clad with nickel chromium-iron alloy, for surfacing steel with nickel-chromium iron weld metal, for dissimilar welding of nickel-base alloys, and for joining steel to stainless steel or nickel-base alloys using the GTAW, GMAW, SAW, and PAW processes.

It is used for welding nickel-chromium-molybdenum alloy (ASTM B 443, B 444, and B 446 having UNS number N06625) to itself, to steel, to other nickel-base alloys, for cladding steel with nickel-chromium molybdenum weld metal, and for welding the clad side of joints in steel with nickel-chromium-molybdenum alloy using the GTAW, GMAW, SAW, and PAW processes. This filler metal is recommended for applications where the operating temperature ranges from cryogenic to 1000°F [540°C].

Filler metal of this classification is used for welding nickel-copper alloy (ASTM B 127, B 163, B 164, and B 165 having UNS number N04400) to itself using the GTAW, GMAW, SAW, and PAW processes. The filler metal contains sufficient titanium to control porosity with these welding processes.

Filler metal of this classification is used for welding the nickel-iron-chromiummolybdenum-copper alloy (ASTM B 423 having UNS number N08825) to itself using the GTAW and GMAW processes.

ER2209 is used primarily to weld duplex stainless steels which contain approximately 22% chromium such as UNS S31803 and S32205. Deposits of this alloy have “duplex” microstructures consisting of an austenite-ferrite matrix. These stainless steels are characterized by high tensile strength, resistance to stress corrosion cracking, and improved resistance to pitting.

ER385 filler metal is used primarily for welding of ASTM B625, B673, B674, and B677 (UNS N08904) materials for the handling of sulfuric acid and many chloride containing media.

ENiCrFe-3 electrodes are typically welding of nickel-chromium-iron alloys (such as Inconel 600, Inconel 601, Nimonic 75) to themselves and for dissimilar welding between nickel-chromium-iron alloys and steels.

ENiCrMo-3 electrodes typically are used to join a wide range of pitting and crevice corrosion-resistant alloys. The lowest alloyed materials employed with these electrodes are the molybdenum-modified type 317 stainless steels.
