Stick Electrode suits low-hydrogen applications.
December 1, 2008 -
Designed for structural fabricators working in flat and horizontal positions, ExcaliburŽ 7028 features even burn-off, optimal slag release, arc stability, resistance to starting porosity, and puddle control. Charpy V-notch test results typically fall in range of 60-142 ft-lbf at -40°F, which exceeds minimum fracture toughness required for variety of structural welding applications, including ships and bridge structures, storage tanks, and general heavy industrial fabrication.

Lincoln Electric Launches New Excalibur 7028
Low-Hydrogen Stick Electrode Offers Structural Fabricators Higher Deposition Rates and Faster Travel Speeds
o High-speed, high-deposition electrode designed for low-hydrogen applications in the flat and horizontal positions
o Smooth, consistent operation over a wide current range
o Excellent slag release, arc stability, resistance to starting porosity, and puddle control
Cleveland - Lincoln Electric announces the addition of the new ExcaliburŽ 7028 low-hydrogen stick electrode to its premium line of ExcaliburŽ mild steel stick electrodes. The ExcaliburŽ 7028 electrode offers the same superior operating characteristics of the ExcaliburŽ line with the enhanced capabilities of higher deposition rates and increased travel speeds.
This electrode is designed specifically for structural fabricators working in the flat and horizontal positions. Applications for ExcaliburŽ 7028 include ships and bridge structures, storage tanks and general heavy industrial fabrication jobs.
Smooth, Consistent Arc Characteristics
Smooth, even burn-off, easy re-strikes and a clean weld puddle make ExcaliburŽ 7028 the ideal choice for maximum operator appeal. The excellent arc characteristics of ExcaliburŽ 7028 across a wide current range give welders the ability to deposit fillet and lap welds without undercutting. The superior operability of ExcaliburŽ 7028 makes it easy to repeat high quality, consistent welds.
Deposit Characteristics
ExcaliburŽ 7028 Charpy V-notch test results typically fall in the range of 60-142 ft-lbf (84-193 J) at -40°F (-40°C), which exceeds the minimum fracture toughness required for a wide range of structural welding applications. This exceeds AWS minimum requirement of 20 ft-lbf (27 J) at 0°F (-18°C). In addition, this low-hydrogen high speed, high deposition electrode meets AWS H8 diffusible hydrogen limit.
ExcaliburŽ 7028 is available at a welding supply store near you. Or, call (888) 355-3213 or visit www.lincolnelectric.com to learn more.
The Lincoln Electric Company, headquartered in Cleveland, Ohio, is the world leader in the design, development and manufacture of arc welding products, robotic arc-welding systems, plasma and oxyfuel cutting equipment and has a leading global position in the brazing and soldering alloys market.
