Postalloy® 219HD Tubular Electrode


When protection with tungsten carbide is needed, Postalloy® 219HD is an ideal choice. Weld deposits contain tungsten carbide in a chromium cobalt rich matrix, providing a good combination of abrasion resistance with impact toughness. Other features include:

  • Low amperage and high metal recovery - no slag to chip
  • High deposition rates - up to 3 times faster than ordinary electrodes
  • Moisture resistant coating, even under severe weather or high humidity

Postalloy® 219HD hardfacing is a unique concept in hard facing technology and is over 90% efficient. It's tubular design offers very smooth operational characteristics and permits higher travel speeds and much higher percentages of carbide forming elements contained in the core as compared to ordinary flux-coated electrodes.

Welding Procedure:

Remove old hardfacing and any fatigued base metal. Postalloy® 250 gouging electrode is useful for this purpose. Preheat from 200-400 °F (93-204 °C) is recommended for steels with a carbon content of .25 to .45. Steels with a higher carbon level should be preheated from 400-700 °F (204-371 °C). Do not preheat austenitic manganese steel. Use a minimum arc length equal to about the diameter of the electrode. Hold the electrode at 90° to the work surface for proper application. Do not apply more than two layers. On manganese or hardened steel, an intermediate or cushion layer of Postalloy® 207 is recommended.
