Recommendations : Re-dry the electrodes at 350^oC for one hour or at 250^oC for two hours. Keep the re dried electrodes in a holding oven having 120^o-150^oC temperature. Use the electrodes directly from the holding oven. The pre-heat and Inter pass temperature should be maintained at 160^oC - 190^oC. The welded section should be stress-relieved at 690^oC at-least for one hour.
