Welding Rods, Wire and Electrodes
Metal-Cored Wire is suited for robotic MIG welding.
Press Release Summary:
McKay® GOLDCOR® 309LSi metal-cored gas-shielded stainless wire joins common austenitic stainless steels (309L alloys) or 300 series stainless steel to carbon or low alloy steels. Product's arc produces concave bead profile and allows for single- and multi-pass welding. Suited for vertical down (30°-60° incline) welding, wire offers deposition rates from 8.0-20.22 lb/hr with .045 in. dia wire to 7.5-27.0 lb/hr with 1/16 in. dia wire.

Hobart Brothers GOLDCOR® 309LSi Metal-Cored Wire Increases Productivity, Reduce Costs
-Provides increased travel speed and higher deposition rates -Ideal for joining austenitic stainless steel to carbon or low alloy steel -Useful for overlaying carbon and low alloy steels -Specially designed for automotive exhaust fabrication
TROY, Ohio. September 16, 2004-For robotic MIG welding in automotive exhaust fabrication, Hobart Brothers has introduced the McKay® GOLDCOR® 309LSi metal-cored gas-shielded stainless wire. Used to join common austenitic stainless steels (309L alloys) or 300 series stainless steel to carbon or low alloy steels, the 309LSi has a moderately soft arc that produces a concave bead profile and allows for single- and multi-pass welding. The wire is good for vertical down (30 to 60 degree incline) welding and for overlaying carbon steel and low alloy steels.
Hobart Brothers designed the 309LSi wire to operate with a 98 percent argon/2 percent oxygen shielding gas in the spray transfer mode for automotive exhaust fabricators that have poor to fair fit up. GOLDCOR 309LSi, a metal-cored wire falling under AWS (American Welding Society) classification A5.9 Specification for Corrosion Resisting Chromium and Chromium-Nickel Steel Bare and Composite Metal-Cored Welding Electrodes, offers all the advantages of metal-cored wires, including low spatter and reduced slag.
Increased productivity, Reduced Costs
Hobart Brothers designed the McKay 309LSi wire to provide increased travel speeds and higher deposition rates, along with improved gap bridging. These features, says Jennifer Monnin, Hobart Brothers product manager, make the wire appealing for fabricators. "In the automotive exhaust market, you get a lot of poor fit up. The 309LSi's arc enables this wire to fill gaps with exhaust parts at an increased travel speed than that of a stainless solid."
In addition, operators will find that the 309LSi has 25 to 30 percent higher deposition rates than solid wire, with low spatter and little to no slag. The wire's deposition rates-8.0- to 20.22-lbs/hr. with the .045-in. diameter wire and 7.5- to 27.0-lbs/hr. with the 1/16-in. diameter wire-help increase throughput time and lower production costs.
Operating well in flat and horizontal positions, in addition to vertical down, the wire's welding parameters are185 to 340 amps (DCEP) and 22 to 29 V for the .045-in. diameter wire and 200 to 450 amps (DCEP) and 25 to 34 V for the 1/16-in. diameter wire. Both diameters of the 309LSi wire are available in 30-lb. spools.
