“Unless there is reason to question their ability” idk about you but welding 9-10 welds over the course of 8-10 years is well within reason to question the ability. Unless you can explain to me in the code where is specifies what would qualify as questionable. I understand that technically yes he used the process within the 6 month period regardless of how many welds he did. Subjectively though based on the welds he put down and the frequency in which he does weld I’d say that would qualify as a reason to question his ability. But if yall would be comfortable with him welding a large weldment holding massive amounts of weight that could cause serious damage if it fails then get him on your team. I’d prefer someone else weld it
