There is a 26” pipeline. The mainline is 26” X65. The receiver and valve sites will have X65 to Grade B / X42 fitting coming off of the barrels. So, there will be fillet welds that are X65 to X42/Grade B.  Is the welder qualified if he takes a X52 (12”) butt and (12”) branch?

Yes, as long as the variables in  6.3.2 are satisfied (20th Edition) - process, progression, electrode group.
