For what it’s worth, that’s how a lot of critical welds are verified. X-raying welds is fairly standard practice in the field if the strength of the weld is important enough. And it’s not as much about trust as how much it is fairly easy to make a mistake while welding and not know it. A good welder paying close attention can tell whether a weld is good with fairly high accuracy. But that’s not always enough certainty and when skilled honest people make mistakes here, they won’t nevessarily know it. So, you X-ray.
