Lincoln Electric announces the addition of the new Excalibur 7028 low-hydrogen stick electrode to its premium line of Excalibur mild steel stick electrodes.

The Excalibur 7028 electrode offers the same superior operating characteristics of the Excalibur line with the enhanced capabilities of higher deposition rates and increased travel speeds. This electrode is designed for structural fabricators working in the flat and horizontal positions. Applications include ships and bridge structures, storage tanks and general heavy industrial fabrication jobs. Smooth, even burn-off, easy re-strikes and a clean weld puddle make Excalibur 7028 the ideal choice for maximum operator appeal.

The excellent arc characteristics across a wide current range give welders the ability to deposit fillet and lap welds without undercutting. The superior makes it easy to repeat high quality, consistent welds. Excalibur 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.
