The Process of Strip Weld OverlayAs many industries require equipment to work at elevated temperatures, in corrosive media andunder high pressure, the use of highly alloyed materials for the fabrication of completecomponents becomes financially unrealistic as their size increases. One solution for stainlesssteels and other highly alloyed materials, such as nickel base alloys, is to deposit a weld overlayon the surface of the equipment to resist corrosion attack.Dual-material clad plate utilises a thin layer of the costly higheralloyed material which is in contact with the corrosive media,while the lower cost substrate is used to give the desiredstructural integrity. The application of the high alloyed layercan be accomplished by several methods including, dual rolling,explosive bonding and weld overlay. However the most flexibleof these methods is weld overlay.Weld overlay gives the designer and fabricator flexibility to choosea wide variety of load bearing materials as substrates, as well asa wide variety of wire/strip chemistries to deposit the required overlay.In general, the use of weld overlay to surface finish shaped componentseliminates the eventual problems arising with cold or hot forming.All the welding processes can be utilised, however due to constraintsin the physical requirements, some are better suited than others.Strip Weld Overlay ProcessThe initial use of a strip instead of a wire withthe submerged arc process, was patentedin the US around 1922. Due to thedevelopment of the nuclear industry, thisprocess became industrial, and is nowconsidered as a mature process.Several modifications of submerged-arcwelding with strip have been developedmainly with a view to further increasing thedeposition rate and to decrease the dilution.There are two strip processes: SubmergedArc Strip (SAW) and Electroslag Strip (ESW).Among all the welding processes,submerged arc and electroslag strip weldoverlay offer the highest deposition rate, thebest bead characteristics and trouble freeoperation using standard SAW weldingequipment.The Submerged Arc Strip process(SAW Fig. 1) uses an arc that runs back andforth at high speed along the strip, meltingthe strip, the base metal and the flux toobtain the overlay onto the base material.Because this is an arc process, there ispenetration into the base material resultingin dilution levels of ~20%. For a strip of60 mm, deposition rates are in the regionof 12-14 kg/hr.The Electroslag Strip process (ESW) Fig. 2ignites like the submerged arc process.When a sufficient amount of flux is melted,because the molten flux has a lowerelectrical resistance than the electric arc, thecurrent flows through the shallow layer ofconductive slag, and the arc is extinguished.The process produces sufficient heat tokeep the process stable and to melt thestrip into the liquid slag; which istransferred into molten metal depositedonto the base material.The ESW process has significantadvantages over its SAW counterpart:1. As there is no arc present, there islimited dilution into the base material,typically 10% (compared with 20% forSAW using 60 x 0.5 mm strip). Thisleads to the ability to deposit singlelayer full chemistry with over alloyedstrip, even when a low carbon gradeis required.2. Due to the smooth operation of thisprocess, higher current levels can beused resulting in deposition rates upto 40 kg/hr for 60 mm strip.3. Electroslag refining occurs when themolten metal passes through the slagbath, resulting in cleaner weld metalwith a lower risk of hot cracks, evenfor fully austenitic deposits.4. The electroslag process cannot beused with carbon steel strip, becauseof the higher electricity conductibilitythan stainless or nickel strip.Fig. 1: Submerged arcprocess weld overlayStrip feed systemFig. 2: Electroslagprocess weld overlayStrip feed systemFlux supplyFlux burdenStick out(30-40 mm)BasemetalLiquidslagStripLiquidmetalElectricalpick-upFluxsupplyPenetration(0.3 - 0.5 mm)WeldoverlaySolidified slagThicknessof overlayFlux supplyFlux burdenStick out(30-40 mm)BasemetalLiquidslagStripElectricalpick-upLiquidmetalPenetration(0.3 - 0.5 mm)WeldoverlaySolidified slagThicknessof overlayTravel direction of the headTravel direction of the head4

General Considerations: Welding Parameters2005-502Current and welding speedIn weld overlay, the requirement is to deposit an alloy which isquite different from the base metal. If the 2 main parameterswhich govern the dilution are the current and the welding speed,other parameters also need to be taken in consideration:voltage, stick-out, size of strip, and in the case of circumferentialsurfacing, the strip position related to the diameter of the workneeds to be controlled.For a stainless steel strip of 60 x 0.5 mm, all other parametersremaining constant, when the current increases, the thicknessdeposited increases and the dilution decreases.Fig. 3, illustrates the influence of the current and the weldingspeed on the dilution and the thickness deposited.Fig. 3: Dilution and thickness related tocurrent and welding speed% Dilution242220181614121081,5 m/min(1250 A)(~24 kg/h)2,5 m/min(1800 A)(~36 kg/h)Thickness(mm)654VoltageGenerally the voltage should be set between 24 V and 25 V,as an excessive voltage generates spatter and too low a voltageinduces current instability.Stick outStandard stick out is around 30-35 mm, a short stick outgenerates spatter, an increase of stick out from 30 mm to 50 mmwill reduce the dilution level slightly (e.g. from 10% to 8%) but thesmoothness of the surface deteriorates.Size of stripWith the same current density, typically used in ESW:~ 40 A/mm², as the width of the strip increases, the dilution leveldecreases: ~12% for a strip of 30 mm, ~10% for a stripof 60 mm and ~9% for a strip of 90 mm.Number of layersDuring the welding of the first layer, the deposit is generally quitedifferent from the base material, but for the subsequent layers,the deposit is generally similar to the first layer. For the ESWprocess, when a first layer is welded with a strip type 309L, on acarbon steel plate, with typical parameters, the dilution is about10%, the second layer, welded with same parameters, will havea dilution around 25%.648 10 12 14 16 18 20 22 24 26 28 30 32 34 36 38 40 42 44 46Magnetic steering deviceMagnetic steering is used to reduce the risk of lack of fusionat the overlap, and to increase the flatness of the surface of thedeposit.Strip positioning1,5 m/min 1,5 m/minWhen working on a curved surface, the molten pool is relativelylarge, and the liquid slag and the liquid metal have the tendencyto flow to the lowest point of the curved surface. Thus, theposition of the strip will have a big influence on the dilution leveland on the profile of the bead. This effect takes place when thediameter becomes smaller than 3 metres, the smaller thediameter, the bigger the influence.For more information about these parameters,please contact OERLIKON Service.Welding speedcm/min35

General Requirements of the Overlay2570-255000-0365Specifications generally require a ferrite level on the surface and chemical composition at a specified distancefrom the surface. The deposit will pass corrosion resistance and guided side-bend testing after post weld heattreatment. If the equipment is required to conform to ASME IX code, reference should be made to QW-214Chemical analysisGenerally, the specified chemical analysis is required to conformto the composition for the undiluted weld metal of the equivalentAWS grade MMA electrode.For applications in the petrochemical industry, the requiredanalysis needs to be controlled at -3 or 3.2 mm bellow thesurface of the deposit.For applications in the nuclear industry, the requirement is generallyfor the undiluted weld metal from the “strip -flux” combination.Ferrite levelFerrite level is generally indicated in FN (Ferrite Number) and iscalculated using the WRC 92 diagram or measured on thesurface of the deposit, in the as welded condition, with acalibrated instrument.For petrochemical industry applications, a minimum ferritenumber is specified, FN 3 to 5, to avoid hot cracking, and amaximum ferrite number is specified, FN 8 to 10, to avoid acontinuous band of delta ferrite, where sigma phase can beformed during PWHT.In case of specific corrosive environments such as ureaspecifications, ferrite should be minimised, FN

AST and ELT fluxesSimilar to other welding processes, the most sophisticated components are the coating of an MMAelectrode and the flux for the submerged arc process, which determine the quality of the weld deposit.Welding fluxes are characterized by their basicity, granulometry and composition. The most importantcharacteristics of the liquid slag which is formed during the process are: viscosity, solidificationtemperature range, surface tension and interaction with the chemistry of the deposit.For many years, the extensive R&D commitment of OERLIKONhas continued to contribute to the knowledge of raw materialsand experience in flux formulation used in both the submergedarc and electroslag processes.Generally, submerged arc fluxes contain small quantitiesof alloying elements, mainly Cr, to compensate burn-out dueto the electrical arc. In the electroslag process, there is no arc,the burn out of Cr is hence reduced. No alloying elementsare required and these fluxes are neutral. In some cases,when specific strip compositions are not available,compensated fluxes are required to reach specific analyses.The main characteristics for electro slag fluxes are a largequantity of fluoride and very low silicon oxide content.Due to the large quantity of fluoride, these fluxes are ableto form a shallow layer of electrically conductive molten flux.Due to the very low silicon oxide content, the deposited metalcontains an extremely low oxygen concentration anda high degree of purity in terms of levels and size of non metallicinclusions. This is important for obtaining a good resistanceto pitting corrosion.OERLIKON DRYBAG and METAL DRUMS packaging arecompletely moisture proof requiring no controlled climaticconditions and as such can be used for welding without anyreconditioning or re-baking. Before use, the packaging integrityshould be checked. If the bags or drums show signs of puncturethen the contents must be re-dried or discarded.2007-4740109-33_retFluxes for the Submerged Arc ProcessDesignation Classification FeaturesAST 100 BAST 300AST 600ISO 14174 -S A CS 3ISO 14174 -S A CS 2BISO 14174 -S A AB 2BAgglomerated and alloyed flux (nickel and molybdenum) for strip weld overlay applications using the submergedarc process.
