THE SUBMERGED ARC WELDING PROCESSTHE SUBMERGED ARC WELDING PROCESSThe arc being shielded and hidden under the flux, high current density can be consideredwith the following benefit: Operator protection from arc ray and heat radiation High deposition rate and high quality welds Versatile welding process with combination of wire diameter, flux type, single ormultiple electrodes, welding current wave shape and welding modeWELDING PARAMETERS (VARIABLES)WIRE DIAMETER/AMPERAGEThe submerged arc wire standard portfolio includes different wire sizes, mainly between 2.0 and4.0 mm wire diameter. The choice of wire size is made in accordance with the welding procedureparameters in order to maximize the current density and increase the melt off rate, withoutexceeding the wire current carrying capacity as shown in the following table.Amperage UsedWire Diameter2003004005001.93.04.56.76007008002.0 mmkg/h2.4 mmkg/h2.94.45.98.03.2 mmkg/h2.53.85.26.78.54.0 h2.02.4 mm kg/h2.4 mm kg/h3.2 mm kg/h3.2 mm kg/h4.0 mm kg/h4.0 mm 86442200200200300300400500600400500600Amperage UsedAmperage Used8SUBMERGED ARC WELDINGwww.lincolnelectric.eu900

THE SUBMERGED ARC WELDING PROCESSELECTRICAL STICK OUTElectrical Stick Out setting:The electrical stick out or CTWD (contact tip to work distance) is the distance set between thecontact tip end and the work piece. The stick out needs to be kept constant along the weld ifconsistent results are expected for the welding behavior and penetration.The Long Stick Out variant:Taking benefit of the Power Wave technology, the long stick out variant is now a reliable optionfor a number of applications.Unmatched ProductivityIncreaseCompleteControlEnabled by State-of-the-ArtEquipment Increase deposition rate Power Wave technology Power Wave AC/DC 1000 SDwithout changing the process Significant reduction of heatinput possibleeliminates arc strikingissues by allowing completetailoring of the arc startcharacteristics MAXsa 10 Controller MAXsa 22 Automatic Feeder Precise control over the inputWATCH VIDEOof energy into the weldHEAT INPUTHI A V v Heat Input [kJ/cm]Current [A]Voltage [V]Travel Speed [cm/min]HI 0.06 x A vx VThe heat input will affect the mechanical properties of the deposited metal as well as the basematerial in the heat affected zone. It is also a key parameter for the distortion of the weld assembly.As an example, a target at 20 kJ/cm for single arc procedure on non and low alloy grade is a good start.With the Power Wave AC/DC 1000 SD, the heat input can be optimized and tailored as needed.10SUBMERGED ARC WELDINGwww.lincolnelectric.eu

From the procedure adjustment to the hardautomation investment, it is our philosophy to partner with the customer to achieve the highestsavings combined with an optimum ROI (return on investment).Improving productivity in the workshop should be considered from many aspects:WELD PREPARATIONV, X and K joint The included angle ranges between 45 and 60 The narrower angle is used when the top of thepreparation can be reached in one passHeavy plates Combined preparation also called a compoundbevel is used to limit the groove area andguarantee penetration– 60 angle at the bottom– 5 to 15 above as soon as the bevel sidedistance exceed 12 mm–M achining and seam tracking system ismandatoryDouble side welds Symetric preparations are always moreeffective than asymetric grooves Up to 25 mm, it is possible to use the two runtechnique (1 pass each side in tandem)www.lincolnelectric.euSUBMERGED ARC WELDING11
