It is quite common to RT these for "end gap". BUT, can socket welds be RT'd for defects under B31.3 or 31.1?
I seem to recall some elliptical shots on s/w years ago, but memories can be (and often Are) distorted over time. Is there any difference between this and shooting a 1" girth weld.
If there is access to two sides it can be shot. Getting code acceptable coverage is another story. CR may can do it, but I would still have a lot of doubt until I saw it proven on a mock up. Then there is the pod on one or the other fusion lines depending on angle. I could be proven wrong, but I just don't see it as viable.
Yeah, it's that "Code acceptable coverage" hurdle that no one will get on board with.
So to prove it, then it would require a battery of samples with induced defects such as mechanically drilled "porosity" and saw cut linear indications, then shot from various angles?
Geeze, the things that keep me up at night...
On occasion various customers have requested random radiography "for information" of socket welds, and it can locate some flaws but it is not reliable on a consistent basis because of geometry or possibly access or obstructions. I suppose they are after the warm, fuzzy feeling... or maybe feel some inspection is better than none. Personally I think the possibility (or threat) of random radiography might make some welders a little more conscientious of their workmanship, however many welders use the same skills regardless if inspection is utilized or not.
