SA-516 Gr 70

[Kishore S]

Dear sir 

what are the step to find an electrode for SA516 gr 70 in the internet they have mentioned E7018 but as per the SAIL TEST CERTIFICATE tensile strength is 79ksi so what electrode do I have to use   

[Rameshbabu B]

E 7018 is the correct one. The sail test certificate mentions the observed values nothing to worry about it.

Dear Kishore,

Based on the tensile strength 79 KSI. You can use  low hydrogen electrode E8018

E7018. If you have plan to do normalizing after welding go for E8018

SA 516 Gr 70 Means 70KSI  or 490 MPa is minimum UTS required was per SA 516. for these plates.

Compatible electrode  is E7018  as 

minimum UTS of this electrode is 70KSI minimum or 490MPa minimum. 

This is Welding and Material Technology compatibility and acceptable to Code requirements.

u have to match minimum tensile strength. in ur case, 516 gr 70 means minimum tensile is 70000psi or 485 Mpa. To match this, u can very well use 7018 which is 70000 psi or 485 Mpa. U are not supposed to match with actual tested value because it will vary.

Dear Kishore , 

consuamble selction is mainly depends on  Base metal  tensile properties , Specification and service requirements(Hardness and impact requiremnts). other facrtor also to be taken into considered in case if you wan to fo with different welding processes ,in your  case it is already SMAW process  and  base metrial is  SA 516 Gr 70 means minimum specified tensile strength is 70000psi /485 Mpa. while selecting consumable you need to consider the minimum specified stregth of the base metal not acutal tensilet stregth  specified in MTC , so the recommended  electode for this purpose is E7018 which satisfys the base mental strength requirement for impact requirements to be confirmed by manufaturer based on your project requiremnts, over matching consuambes are not required in this regard as many of the applications E7018/E7018-1 will suffice the requirement of cleints .

in some applications if your project impact reuirements are at below -46deg C you may need to choose E8018/E8018-C3 elctrodes.

Thanks & Regards,

In addition , pl check whether it is subjected to PWHT, if so, basically 15mps will be lost due to SR, in that select 7018-1
