[PSUBS-MAILIST] root pass

[Daniel Lance via Personal_Submersibles]

Brian,
7010 is a good choice  if you choose to do a smaw (stick ) root pass . I
would refrain from using 6010 because of its lower tensile strength
especially if  you are welding 516 gr 70. Have you considered TIG welding
your root passes ? 70s filler wire would be best in that case.
