SÜA - E312-16 - Stainless Steel Welding Electrode - 14" x 1/8" (0.5 LB)

Excellent for welding dissimilar metals, especially if one of them is stainless steel of high nickel content. Perfect electrode to use on unknown steels. All-position welding on difficult to weld steels such as manganese steel, air-hardening steels, armor steels, spring steels, tool and die steels, rail steel, and aircraft steel. ***READ THIS: The images are for reference only. Please check Picture #2 for an approximate quantity of electrodes per pound*** Used as a wear-resistant build-up or buffer-layer option in hard-facing applications. Creates a two-phase weld deposit with substantial amounts of ferrite in an austenitic matrix; this two-phase deposit makes it highly resistant to weld metal cracking or fissures. Weld deposits are ductile, porosity-free with greater root penetration, and produce the highest tensile strength of standard stainless steel electrodes. Popular applications include repair of construction equipment, repairing or modifications of dies, broken machinery repairs, and joining wear plates. These Electrodes are available in Sizes: 3/32" and 1/8" - Available Packages: 0.5 Lb, 1 Lb and 2 Lb - Select your option from the Size Menu - Check Picture #2 for an approximate number of electrodes per pound - 3/32" electrodes are 12" long and 1/8" electrodes are 14" long Instructions: Use DC+ (reverse polarity), however, an AC machine with sufficient open-circuit voltage may be used. Bevel thick sections to a 60 degrees Vee. Clean the weld zone of all contaminants. Preheating 300 series stainless steel is NOT required. The diameter of the electrode chosen should be equal to the thickness of the base metal. Use the lowest possible welding current or increase your welding speed in order to avoid overheating or distortion of the base metal. Overheating stainless steel can degrade its composition and corrosion-resistant properties. The arc length should be kept as short as possible but do not touch the flux-coating of the electrode into the molten weld pool. Hold the electrode at a 15 angle into the direction of travel. Stringer beads should be used in the flat, horizontal, and overhead positions. The weaving technique should be used for vertical welding but not to exceed two to three times the diameter of the electrode. Remove all slag before making additional passes. On the final pass, allow the part to cool down partially before removing the slag, then promote rapid cooling by quenching with a wet rag or compressed air. This will preserve the corrosion-resistant properties of the 300 series stainless. Do not allow to slow cool.
