Not correct – stainless steel SMAW electrodes -15, -16, -17 are low hydrogen electrodes and are hygroscopic. Once the hermetically sealed containers are opened, the electrodes must be stored in an oven like other electrodes. While 300 series materials are resistant to hydrogen assisted cracking, inadequately dried electrodes can result in weld metal porosity.

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 refered manufacturer recommendations.

Generaly SS. Electrodes are recomended 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 problm of peelng of flux coatinhg

Pl let me.. wat it is?
Thanks
