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. The 1/4" (6.4mm) diameter can be used for vertical and flat position welding. The 3/8" (10mm) and 1/2" (12.7mm) sizes should be used for flat only. 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.
