1. As long as the other radiograph butt weld is acceptable it’s ok, as the 10% condition percentage required by the specification code has been satisfied
2. This is usual practice as 10% NDT is really not important
3. Review the original failed weld and insist they have the additional 2 welds radiographed
4. Review the original have it failed weld and repaired , radiographed , then I would insist that they have an additional 2 weld radiographed
