Does anyone has some experience with the inspection of Friction Stir Welds? The specific task is to inspect 3.5mm Al butt welds.
I've read some articles about phased array probes but I'm looking for a way to go without these expensive things. The detection of 'regular' flaws like voids and cracks works reasonably well but the detection - and the production - of 'kissing bonds' doesn't work satisfactorily so far.
If anyone got some experience on that field I would appreciate all thoughts.
Thanks in advance
