Ultrasonic testing grades

Can anyone tell me how the grading works in UT?

eg, What is a 3.1? Is that just a level one? so what would a 3.2 be? or a 3.7 etc etc

i goes something like this:
3.1 is for plate butt welds
3.2 is for pipe butt welds
3.7 for t-joints
3.8 for nozzles

(that may be a little wrong but thats the concept)

when doing the exam you have to do test pieces of each type so you can fail 3.8 but still pass 3.1 meaning you can test plate bw's but not nozzles etc

not quite. level III is a step up.

3.1, 3.2, 3.7 & 3.8 are all level II grades. You also get Level II grades for testing cast and wrought products.

If you pass 3.8 you will still be a level II but just cleared to test more weld configurations.
