[MW:11579] RE: electrode

Hello Llangkumaran,

 

ER -70S-2(GTAW) & E-7018 (SMAW) both of the welding consumables are compatible with SA 106GrB and SA 333 Gr-6 materials. As of the of the base metals have 60 ksi nominal UTS, the above consumables would safely meet the above strength requirements. Some additional points I would like to ask are :-

• design code
• design metal temperature
• PWHT-yes or no.

Thanks.

Dear experts,          Can we use ER 70S-2/ TIG welding filler wire for root weld and E 7018/SMAW electrode for both materials ie SA 106 Gr B and SA 333 Gr 6 as their PNO and GNO same? if not why? kindly refer codes if any.   Regards Ilangkumaran
