Lincoln launches low-hydrogen stick electrode

Lincoln Electric has announced the addition of the Excalibur 7028 low-hydrogen stick electrode to its line of Excalibur mild steel stick electrodes.

The Excalibur 7028 electrode offers the same operating characteristics of the Excalibur 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 Excalibur 7028 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 suitable for maximum operator appeal.

The arc characteristics of Excalibur 7028 across a wide current range give welders the ability to deposit fillet and lap welds without undercutting.

The 7028 is able to repeat high quality, consistent welds.

Excalibur 7028 Charpy V-notch test results typically fall in the range of 60-142ft.lbf (84-193J) at -40F (-40C), which exceeds the minimum fracture toughness required for a wide range of structural welding applications.

This exceeds AWS minimum requirement of 20ft.lbf (27J) at 0F (-18C).

In addition, this low-hydrogen electrode meets AWS H8 diffusible hydrogen limit.
