Inspection of Spot Welds was several times discussed in this Forum,
however it is still interesting to discuss what's new.
You may use the Forum Search to find the previous discussions.
Articles can be found with the article power search also.
Anyway, something new was published recently at the annual DGZfP conference May 1999 in Celle.
See below the German abstracts:

Very good information Rolf pointed out. I have some experience with
UT inspection in spot welds. If you need further information let me know.
Regards.

We have scanned spot welds with a short pulse transducer (100 ns pulse length) and it works very good.
We can make a hand-held scanner for this purpose (we have designed and made similiar scanner for investigation of soft palate,
see please: http://www.optel.com.pl/article/english/plate.htm).

you may try the panimetric sonopen. it is small enough to go directly onto the spot and it has a short focal point.

Make sure you have an appropriate pulser and receiver to drive correctly 20 to 25 MHz probes. There are some instruments with almost automatic evaluation.
