Recommendations :

Redry the electrodes at 350oC for one hour or at 250oC for two hours. Keep the re-dried electrodes in a holding oven having 120o to 150oC temperature. Use the electrodes directly from the holding oven. The pre heat and inter pass temperature of 160o - 190oC is recommended. The welded section has to be stress relieved at 690oC at least for one hour.
