Welding electrode storage
Welding electrode storage
(OP)
Can anyone point me in the direction of some information of welding electrode storage requirements? I am currently looking over a proposed procedure for filler metal identification, storage, and handling and need something to verify the data against. An example of the data being verified is the amount of time a low hydrogen electrode can be out of an oven prior to use, or the minimum oven temperature for a low hydrogen electrode after removed from original can.

My 1997 AISC Seismic does not have the appendix but try the 2002 AISC Seismic. The reference above is from a slide presentation in a recent welding seminar I attended.

I don't have access to my AWS codes right now, but the TxDOT field welding requirements pretty much repeat the D1.5 requirements:

This is likely to be stricter than whatever code you're supposed to be working to.

These are Max hrs exposed to atmospheric conditions before a rebake is required. If no rebake, discard.
The above electrodes need to be held by the welder in quivers and not the their back pocket. You can use a portable rod box to minimize the number of exposed rods.
I'm trying to rcall my welding books so I can give you temperatures to hold and bake. The manufacturer's literature will also give you the information.

If it moves, train it...if it doesn't move, calibrate it...if it isn't written down, it never happened!

AWS D1.1 is a standard that I investigated in a MSc program. The bake temperatures are roughly 375C-430C. Times about 1-2 hours. It varies depending on the electrode classification and strength.
If you store them I recommend that you store them at 200C. 120C is "code acceptable" but my experience was that hydrogen levels crept upwards. 200C held them flat. This was consistent across 3 manufacturers.
