Just a note if you are just getting started with this NDE program:
...make sure to get your Level III(in-house or contract) to write your "Written Practice", "UT inspection Procedures", then he/she(LevIII) can test your UT guy to your procedures and after said UT guy has satisfied all of the required classroom, training, and hand-on hours then you can get him out doing the inspections by himself. Same goes for PT, MT if you plan to add any of those methods at a later date.
If you need any help with any of this, don't hesitate to holler...many of us here have been through all of this at one time or another. I've been bouncing sound myself for a few years now. Heading out the door to UT a full pen column base plate to column shaft in a few minutes.
