Dear experts,
1) i want to learn that is there any option of E6010 in root welding of pipe by SMAW available ? i do know that same E6010 used for API 5L grade B, 42 and upto grade 60 also.
2) If we use E7018 in root (when it suits UTS of base metal) , what is the main problem ? is it only about slag in inside face and penetration ?
3) Why E6010 is AWS SFA 5.1 and same E7010 is AWS SFA 5.5 (both looks same except UTS) ?
please answer in details.
Regards,
sam.
