Please anyone explain that how long

Please anyone explain that how long electrodes are kept in holding oven and which ASME code states that

Try asking in the welding forum if you mean welding rods.

If you don't provide more details.

Remember - More details = better answers
Also: If you get a response it's polite to respond to it.

There is no maximum time for holding coated electrodes in a holding oven defined in ASME Codes. Check with the electrode manufacturer. We have held low hydrogen electrodes for months in temp controlled ovens.

Most shops have a procedure that defines the minimum time that they require. I have seen everything from 2hrs to 12hrs.

It would be great if you could fill in the subject heading correctly.

300 °C ? limited time for basic rods! Mostly in the 2 - 3hr range. This is for baking (once). Mind, there is a limit for rebaking! the 12 hr Ed says, would probably be linked to rebaking.
few degrees above room temperature (up to 80 °C ): indefinitely, this is to avoid hydrogen pick-up.

No code explain, but it is based on manufacturer recommendation
