Claes Gillenius,
Please let me know how many times re drying is permissible. If electrodes are not used and kept inside the oven, but oven is turn off for overnight.
Regards,
Rafique

If the electrodes are packed in air tight packages they can be used right away. If not, redry the electrodes in the way the manufacturer recommends, normally at a temperature around 300 - 350 °C.
Air tight packages are for example vacuum packages. If such a package is damaged and the vacuum lost, redy the electrodes. Redrying returns the electrodes to it´s original state.

Consult the consumable manufacturer, may be shelf life revalidated with additional testing. Code does not specify the shelf life, but the manufacturer does.

Subject: [MW:3238] Shelf life of Low hydrogen electrodes
Dear All
Our contractor has brought low hydrogen electrodes (E 7018 & 8018) which are manufactured in 2007 for welding station piping in one of our intermediate pump station of our cross country pipeline project. I would like to know whether these electrodes can be used now?. Is there any reference in ASME code regarding the expiry/ shelf life of Electrodes?
Please advise me in this regard.
Thanking you all in advance
Ravindra
Senior Project Engineer
