if re-baking is Permitted for one time only (your specified condidtion ). If found in quivers more than specified time or found exposed to air openly or found in cold disconnected quivers then they shall be discarded.
if re-baking allowed morethan one time as per manufacturer guidelines convence your client for re-baking and such electrodes shall be identified by suitable color coding for tracability on rear stub ends. do the re-baking utilize for welding as usual or else u can use electrodes for welder training / internal infra structure welding works.
Electrodes exposed to the atmosphere for periods less than those allowed by codes or manufacturer recommendations may be returned to a holding oven maintained at specified Temperature and time, after a minimum holding period the electrodes may be reissued

Dear,Most of client specifications and manufacture recommendations says vacuum pack electrodes are opened once after 8 hours it should be bake one time at 300 to 350 dig C.If they are returning those baked electrodes it should be discarded or can use for internal fabrication purpose.Best RegardsSayeedOn Sat, Jul 16, 2022 at 6:34 PM madheswaran s <madhe...@gmail.com> wrote:Dear Experts,I have a question about baking of electrodes. spec or other says backing of electrodes only one time. Now my question is if i received electrodes carton box from manufacturer Like E7018 ok, If baking the electodes then we maintain the elecrodes in holing oven the issuesd to welder for welding, If some electodes are not used , they are exposed in atmosperic condition about 8 hrs, In this case can i do baking again? or already once we backed the elecrode before issuing to welder, so we can't back again? because once only baking permitted. I dont know clear understand ? can anyone help this case.--https://materials-welding.blogspot.com/
