I suppose it is a DE weld. Use 90ksi electrode/Filler Rod as after Normalizing there will be 15-20ksi loss in Tensile strength

Thanks & Regards

Dear Mr.Jayakumar, 

Thank you for the reply. 

Please advise which consumable can be used for SAW welding

Can EH12K and combination flux be used. ??

You can try EA2 wire with suitable Flux in the stress relieved condition by consulting with Welding consumable supplier

Thanks & Regards
