Lincoln Electric's Excalibur 7028 electrode offers higher deposition rates and increased travel speeds

Lincoln Electric has added the Excalibur 7028 low-hydrogen stick electrode to its line of Excalibur mild steel stick electrodes. The Excalibur 7028 electrode offers higher deposition rates and increased travel speeds. The electrode is designed specifically for structural fabricators working in the flat and horizontal positions. Applications for Excalibur 7028 include ships and bridge structures, storage tanks and general heavy industrial fabrication jobs.

Featuring smooth, even burn-off, easy re-strikes and a clean weld puddle, Excalibur 7028 is designed for operator appeal. Arc characteristics give welders ability to deposit fillet and lap welds without undercutting. The operability of Excalibur 7028 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 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.
