SAT requires less post-weld labor....which usually results in lower production costs.
Florence, SC (PRWEB) December 06, 2011
ESAB Welding and Cutting Products introduces Swift Arc Transfer (SAT) – a high-productivity MIG process that utilizes OK AristoRod non-copper coated wires at travel speeds well beyond the limits of normal spray arc welding.
During MIG welding, the welding arc follows a natural sequence as the arc voltage and wire feed speed are proportionally increased; that natural sequence is short arc, mixed arc, spray arc, and rotating arc.
Wire feed speeds associated with spray and rotating arc modes produce a “forced short arc,” but at significantly lower arc voltages. At the higher wire feed speeds associated with the rotating arc mode, but lower arc voltage than the rotating arc mode, the Swift Arc Transfer arc is created.
After extensive research, ESAB has identified many benefits associated with Swift Arc Transfer.
SAT produces flat welds with a good penetration and without undercut. SAT requires low heat input, with results in less deformation.
Swift Arc Transfer requires less post-weld labor due to the limited spatter and deformation, which usually results in lower production costs. SAT is easy to implement and produces a very low amount of silicates.
SAT is suited for fillet and overlap welds in thin to thick plate, in downhand positions. The process has been developed for robotic, automated, and mechanized welding. SAT can operate with a range of wire diameters at several levels of deposition rate.
SAT is best achieved with the Aristo U82 robot package, which includes the power source (Aristo Mig 5000iw inverter or the ESAB Mig 4002, 5002, or 6502 choppers), Aristo U82 control unit with SAT synergic lines, the Robofeed 3004w ELC encapsulated wire feeder, cable packages, and the Marathon Pac bulk drum with wire and optional bobbin holder.
The Aristo U82 robot package can be installed to enable SAT welding on newly built robots and can also be retrofitted to existing installations.
Combined with OK AristoRod non-copper coated wires, SAT yields dependable feeding properties and a stable arc at high welding currents and wire feed speeds. The OK AristoRod non-copper coated wire yields dependable feeding properties and a stable arc at high welding currents and wire feed speeds due to the absence of copper particles that contaminate the feed system.
OK AristoRod is available in Marathon Pacs, which are ideal for high-production environments. Marathon Pacs reduce downtime associated with spool changeovers, and produce better welding results due to the special coiling technique that ensures straighter wire.
OK AristoRod is one of the wires that will soon be produced in the U.S. at ESAB’s new Midway Facility in South Carolina.
