Basic Tips for Thickness Testing with a Flaw Detector

Trying to do a thickness gauge job on a flaw detector budget? Lucky you! Lots of things can go wrong, but let's try to boil it down to the bare minimum shall we? For this video, we're talking mainly about carbon steel at ambient temperatures. If you're working at really high temps, there's a high temp video for that. And if you're working through pesky coatings and want to be as accurate as you can, there's an echo-to-echo video on the channel.

thank you for this refreshing learning video, i need to aske about the impact of using J flank mode in accurate measurements using echo- echo technique, and i prefer always to calibrate the machine on a piece that identical ( same manufacturing condition)with the piece i need to test, the client should provide this, especially when you taking second readings using other machine brand than what has been used in first readings

Are Zero Offset and Probe Delay the same function? Haven't used a Panametrics unit in years but have the USM Go+ now. Thanks.
P.S. Where do I buy the Wave T-shirt you are wearing?

Hi Mr Paul!!like to see all of your UT lesson, anyway sorry for out of this video topic, if you can share a video on a Angle/shear wave twin crystal probe calibration on standard block for it suitable velocity, angle, setting etc. it would be so appreciated!!thank you..

I understand using the pre set velocity. As known values. What’s not known is the affects of scale coating etc… also you say you don’t mind on long distances, but velocity is a minor change on 5900 metres per second. Is that not a long value that a small change wouldn’t matter
