With disconnected LN-8 or LN-9 wire feeders, set the inch speed for the slow rate. This booklet is a brief introduction to thirteen of our best-in-class submerged arc wires and fluxes for joining carbon/non-alloyed steels. 82 recommended Welding Parameters: Flux Cored, Austenitic (3xx-AP) & duplex (2xxx-AP) Stainless Steel - All Position * When using Ar-25% CO 2 for flux cored arc welding lower the voltage by 2 volts The arc is maintained in a cavity of Position the gun over the joint as described under “Gun Operating Positions”. Welding current for submerged arc welding can vary from as low as 50 amperes to as high as 2000 amperes. Hobart Filler Metals provides an extensive offering of wires and fluxes for welding and cladding carbon steels, low-alloy steels, stainless steels, and nickel-based alloys. The first patent on the submerged-arc welding (SAW) process was taken out in 1935 and covered an electric arc beneath a bed of granulated flux. In other words, if you're using a 1/8 inch rod, hold it 1/8 inch from the joint surface. Heat for SAW is generated by an arc between a bare, solid metal (or cored) consumable-wire or strip electrode and the work-piece.

The stick out needs to be kept constant along the weld if Submerged Arc Welding: A discussion of the welding process and how welding parameters affect the chemistry ofCorrosion Resistant Overlays (CRO) 1. Submerged Arc Welding (SAW) • Part 1. If the arc flutters on and off, increase the inch speed.

Product and Procedure Selection. Submerged arc welding is an ‘Arc Welding’ process in which the arc is concealed by a blanket of granular and fusible flux [166, 37]. Submerged Arc. THE SUBMERGED ARC WELDING PROCESS 10 SUBMERGED ARC WELDING www.lincolnelectric.eu ELECTRICAL STICK OUT Electrical Stick Out setting: The electrical stick out or CTWD (contact tip to work distance) is the distance set between the contact tip end and the work piece. Deposition Rates and Weld Quality The deposition rates of the submerged arc welding process are higher than any other arc welding process.

– The SAW welding process. You can increase the length of the arc to reduce heat to the puddle or to limit the deposition of weld metal. Most submerged arc welding is done in the range of 200 to 1200 amperes. As a rule of thumb, in stick welding arc length should match the diameter of the electrode metal. (mm)RangeRangein.

If inch speed is too fast, the wire will tend to stick on starting.
