RE: [MW:13908] use of E 7018 -1 & ER 70S-6 to weld SA 516 GR 70 MATERIAL

There is no issue in using the proposed consumables.

 

Only restrict the Manganese content of GTAW wire below 1.6 % to achieve A No. 1 weld metal chemistry.

 

Thanking you,

Rgds,

Prashant

Dear All,

 

Vessel is being fabricated as per ASME SEC VIII DIV 1.

 

Base material - SA 516 GR 70 HIC - 30 mm Thk. IMPACT TEST not required.

 

  

normally  we are using E 7018 for SMAW,  ER 70S2 for GTAW  & F7P8 EH12K  for SAW Process to weld  above base material.

 

Can we use E7018-1 for SMAW,  ER 70 S6   for GTAW  & F7P8 EH12K for SAW for the above base material.

 

Please Advice.

 

Thanks & Regards
