FEATURES & APPLICATIONS

Structural and repair welds on high strength fine grained steels.

  • Low alloy, high strength AC/ DC electrode for joining low and medium alloy construction steels.
  • Extra low moisture content is below .14%.
  • Smooth running AC/DC coating operates in all positions.
  • Low spatter yield, self releasing slag and uniform rippled deposit.

Welding Techniques: For the majority of materials to be welded with these electrodes, minimum preheats between 212°F (100°C) and 392°F (200°C) are required to avoid hydrogen induced “cold” cracking. Remove all surface contaminants. Maintain a short arc gap and use a stringer or slight weave technique. Chip slag thoroughly between passes.
