How about SDSS Consumables?
Do you have any method of statement for backpurging Module to Modules Integration Joints ( Tie-In), wherer normal sponge methoed not possible.
Is using of soluble dams good alternative?
Thanks

Subject: [MW:7386] MW:7378- Unable to find Oven Baking Temp in ASME SEC 2 C for E309 L - 15

Dear All,
Stainless steel electrodes do not need high temperature re-drying as LAS and C.S electrodes. AWS SFA 5.4 does not address this issue , as it does for C.S and LAS in SFA 5.1(Table-A3) and 5.5(Table-A2).
Re-drying cycle depends a lot on the type of packing and accordingly manufacturer's recommendations. High tech hermetically sealed electrodes (See attached ESAB Catalogue-VAC Pac) could be used straight from the pack or at the most with a re-drying cycle of 150-2000C for one hour. While the ones coming in standard cardboard packing would call for some re-drying based on the storage condition and surrounding humidity levels.
It would be always beneficial to check with the electrode manufacturers on re-drying recommendations unless it's written in the packing.
Thanks.

Dear all
no need backing for SS electrode or any 30 series but you should have to make sure that electrode should be moisture less.

Dear Hegde,
You can see all electrodes pockets they marked baking temperature and duration. Sec II c also referred manufacturer recommendations.

Generally SS. Electrodes are recommended to bake at 250 c for 1.5 to 2 hrs and hold at 100. C till being issued to welder . Higher baking temp. Say 300 c causes problem of peeling of flux coating
