About The LincolnElectric CompanyLincoln Electric is the world’s premiermanufacturer of welding equipmentand consumables. No company onearth is more focused on the everchanging needs of the weldingprofessional. Our business is all abouthelping companies make their weldingoperations more effective, moreefficient, more profitable.Lincoln is truly your “One Source”when it comes to welding. We’re acompany that continually rededicatesitself to the equally important goals ofexceptional quality, and exceptionalservice. Our field support team –– withhundreds of field sales engineers andthousands of knowledgeable andresponsive Lincoln distributors in countries all over the world –– is thelargest in the industry.Innovative thinking. A quality andservice-first attitude. Freshapproaches to design, manufacturing,and packaging. Worldwide strength.That’s Lincoln Electric.What is Hardfacing?The American Welding Society defines hardfacing as "A surfacing variation inwhich surfacing material is deposited to reduce wear." The term surfacing isdefined as "The application by welding. . . of a layer, or layers, of material to asurface to obtain desired properties or dimensions, as opposed to making ajoint."AWS A3.0 Standard Welding Terms and DefinitionsWhat that means to you is that you can use hardfacing consumables fromLincoln Electric to: Get new life out of old parts Hardface new parts (such as on an OEM basis) to get better performancefrom new assemblies Hardface rather than replace partsAnd that extends the service life of your equipment subject to wear, saves youmoney, and sometimes, even makes a service part better than new!What are the benefits of Lincoln Hardfacing consumables? Frequently, the resulting deposit exhibits superior wear-resistant comparedto the original material. Often, the resulting deposit is harder than the original material. When properly applied, the hardfacing or build-up deposit will last longerthan the original material. Lincoln hardfacing and build-up deposits go on smoothly and exhibit betterwear characteristics than many competitive products intended for the sameapplication.Wide Range of Hardfacing ConsumablesWearshield Stick ElectrodesSelect a Wearshield electrode from a broadselection – one for almost any application. Deliver maximum welding application flexibility inremote locations. Compared to other welding processes, requiresthe least amount of equipment. Many Wearshield Stick Electrodes can be usedin all welding positions.Lincore Open Arc Self-Shielded and Gas-Shielded Wire Electrodes andSubmerged Arc Wire ElectrodesChoose a Lincore wire for maximum productivity, especially useful on multiplelayer or repetitive applications. Many alloys, sizes and packages are available. Produces a higher deposition rate than stick. Automatic welding, typically 1/8” (3.2 mm) electrode diameter and greater,requires the greatest amount of set-up, while delivering the highestdeposition rates and maximum productivity.Hardfacing2www.lincolnelectric.com
Lincolnweld Neutral and Alloy Submerged Arc FluxesUse a particular flux to tailor the resulting wear characteristicsfor your particular application. Neutral fluxes do not significantly change weld metalcomposition. Alloy fluxes are used with mild steel wire to make alloyweld deposits. Choosing the right flux can be simple with help from theWelding Experts at Lincoln Electric.Superior FeedabilitySet it and forget it! Lincore wire feeds beautifully, so your hardfacingoperators can concentrate on getting your equipmentback in service instead of on adjustments and restarts.Backed by the best welding company in the worldWearshield, Lincore and Lincolnweld hardfacing productsare designed, manufactured and supported by LincolnElectric – The world’s most respected name in welding.We asked welding professionals what they expect.Then we exceeded those expectations.Why?

After welding is completed, theweldment should be covered and allowed tocool very slowly to near room temperature.Then, once cooled, postweld heat treatmentcan be used to temper martensite andtoughen the deposit.As deposited, Wearshield MM weld metal isnot machinable, although the deposit can beshaped by grinding. Tempering to toughenthe deposit is typically accomplished atabout 800 F (427 C), which will leave theweld metal near 50 Rockwell C. It can beannealed by heating to about 1400 F(760 C) for several hours, followed by slowcooling. Its hardness will then be less than 30Rockwell C. In this condition, it can be easilymachined.To fully re-harden, it is best to reheat toabout 1750 F (954 C) and hold for severalhours to dissolve all carbides and homogenize the steel. Then it can be water or oilquenched (thin sections can be air cooled) toharden, followed by tempering.A preheat and interpass temperature of300-500 F (149-260 C) is usually sufficientto prevent cracking.
