Hard Surfacing ElectrodesHard SurfacingElectrodesHard surfacing electrodes are applied to give steel parts a hard surface layer. TheWearshield electrodes result in a weld metal with a high carbon content also withelements as for example chromium,molybdenum and tungsten. The combination ofthese elements results in high hardnesses. Wearshield electrodes can not be appliedfor welding joints in general.The choice of a surfacing electrode always depends on thetype of wear. Further care has to be taken of the resistance to shock and impact on thesurfaced part. The service temperature of the component plays an important role too.For a correct selection of surfacing electrodes it is important to know that an increasingwear resistance gives a decreasing shock and impact resistance.ElectrodeTypeHARDNESSHRCHBApplicationsConarc 85 25 250Very high resistance against shock and impact loads.Axes, guide rolls, dredge and shovel bucket teeth andchains.WearshieldBU-30WearshieldFrogmangWearshield60(E)35 33040 40060 600Specially for build up and buttering applications. Also applicablefor metal to metal wear.High resistance on metal to metal wear and light abrasionfor bucket links, bucket bases, guide rolls, tractor rolls andcrane wheels.High recovery electrode produces a primary carbide welddeposit.
