Re: [MW:13573] RE: 13556] Welding API 5L X70 By ER 80S-Ni1 + FOX EV 60

in most situations, you will receive numerous suggestions with several
electrodes falls under E80XX. If you are not going with PWHT, i would
rather suggest you to go with E81T1.

To me, TIG process is not suitable for large diameter - 30".
