Good morning! How long has "Electrodes shall be rebaked no more than once" been in existence in the code? Since the 1970's? 1960's?
Thank you and have a great day!!

Welcome to the forum Tammi

I have a 1992 copy of D1.1 and it has guidance/restrictions.  Back then they used the term "redrying" and it is clause 4.5.4

D1.1 1992
4.5.4  Redrying Electrodes " Electrodes that conform to
4.5.2 shall subsequently be redried no
more than one time.  Electrodes that have been wet shall
not be used."

Just for fun; this is from D1.1  First Edition 1972  :)

D1.1 1972:
4.9 Electrodes for Manual Shielded
Metal-Arc Welding
4.9.1 Electrodes for manual shielded metal-arc
welding shall conform to the requirements of the
latest edition of "Specifications for Mild Steel Covered
Arc Welding Electrodes" (AWS A5.1) or to
the requirements of the latest edition of "Specifications
for Low-Alloy Steel Covered Arc Welding
Electrodes" (AWS A5.5) .
4.9.2 All electrodes having low-hydrogen coverings
conforming to AWS A5.1 shall be purchased
in hermetically-sealed containers or shall be dried
for at least two hours between 450 F and 500 F before
they are used. Electrodes having low-hydrogen
coverings conforming to AWS A5.5 shall be purchased
in hermetically-sealed containers or shall be
dried at least one hour at temperatures between 700
F and 800 F before being used. Electrodes shall be
dried prior to use if the hermetically-sealed container
shows evidence of damage. Immediately after
removal from hermetically··sealed containers or from
drying ovens, electrodes shall be stored in ovens held
at a temperature of at least 250 F. E70XX electrodes
that are not used within four hours, E80XX
within two hours, E90XX within one hour, and
EI00XX and EII0XX within one-half hour after
removal from hermetically-sealed containers or removal
from a drying or storage oven shall be redried
before use. Electrodes which have been wet
shall not be used.
4.9.3 When requested by the Engineer, the electrode
manufacturer shall furnish certification that the
electrode will meet the requirements of the classification.

Wow, 1972, thank you! I did also send AWS a message and the answer was "At least 1996".  Some of my guys will be surprised to hear that.  Ignorance is not always bliss.

Let's be clear about something...

I was not using that copy of D1.1 in 1972  (I think Al Moore was though)

I was only a child at that time, and that is still pretty old eh?
Parent - By Tammi30 Date 04-16-2015 18:14
Oh come on now. I was a child in 1972 too.:eek:

In 1971; we didn't even know what an electrode oven was. We used to short the electrode out against the work piece to heat it up to drive the moisture out.

Al,
in 1969
had to buy a rod oven
wish I would have known that:wink:
yes Brent, I have spent $$$$$$$$$$$$ on rod ovens:surprised::lol:
sincerely,
Kent

Kenmore or Maytag,  propane or electric?  :lol:

By the mid 70s we at least had an old refrigerator in the corner with a 100 to 200 watt light bulb (depending on how good the door gasket sealed). I do believe they called them rod heaters though. Electrodes and electrode ovens were only used on nukes and submarines... :lol:

I've worked on a number of jobs where they used a gas range to keep the electrodes hot. They were perfect for jobs where there was little or no electric power. There was just a couple of problems with that method of storing electrodes.

Like lunchtime over flow from the baked beans?  :lol:

Let's just say...I was still young in the early 70's.  Just ask my wife. 

Oh, Tammi,

WELCOME TO THE AWS WELDING FORUM!!

Don't mind us, we wander off topic a lot.  Most of our responses belong in the Off Topic Bar and Grill.  Even some of our threads.
