Mohamed,

One of the most current threads here that should give you lots of info for research is in the 'Welders Exchange' section under the heading 'Rod Box'.  Henry has much info posted there and it is quite a discussion.

Joe,  I don't want to start something negative here, most especially with you.  Your knowledge is far exceeding of mine in these things.  But I can't help but feel as I look at D1.1, Clause 5.3.2.4 that you have these backwards. 

Rebaking is done when the electrodes have been out in atmosphere TOO long and reconditioning is when they are within the allotted time frame and need to be reheated, reconditioned before being reissued. 

Reconditioning done to 5.3.2.2 is at the lower temps, 250*F, for a period of 4 hrs while re-baking of electrodes over exposed is done only once at 500-800*F depending upon exact classification for a period of one or two hrs, again depending upon exactly which classification.

For further clarification, my view anyway, the holding oven is the same as the reconditioning oven.  Rod is put into the holding oven upon opening of the hermetically sealed container but may be issued immediately if it is truly a hermetically sealed container and returned to the holding/reconditioning oven prior to the time limits of Table 5.1.  If the container is not a proper hermetically sealed container or the rods have been over exposed then they must first be exposed to their one time re-bake process and can then be issued for use.

I hope I have seen this correctly.  I'm sure others will jump in, especially if I am wrong.  I look forward most to hear rather Joe and I are on the same page or rather I have misread/understood something in either the code or his post.

Have a Great Day,  Brent
