Re: where to begin in ut Education should never be taken lightly.
There are a variety of on-line education sights that will provide you with a good intro.
This link will take you to the CNDE site. http://www.cnde.iastate.edu/.
Be advised in all educational programs you will only get out as much as you put in.

.Relax, Ian. I did the same thing 20 years ago.Relax, Ian. I took a 5 day level 1 class in UT 20 years ago from Krautkramer and I did just fine with no prior experience. Provided that you have good instructors and training materials, you should do just fine. The level 1 course is an introductory class and you'll learn a lot. Lot's of math involved so if you're strong in that area, it's a bonus.

Ian,
We are running a Level 1 UT training course next month in Sydney Australia. If you go to the Krautkramer website there is a booklet you can download, "Non destructive Testing of Materials - Introduction to Basics" It is a 40 odd page booklet and we find it very helpful for the students.

Regards

Ian, Training is never wasted, but UT is a skill and nothing beats hands on experience. I started in the mid 60's and learnt most of my trade on the job. I have not stopped learning, there is always something new.
Stick at it, work on the probe, ask questions and read up on the subject. Study what you are testing as this helps greatly. Don't be afraid to ask, any operator thats worth anything will help you.
The best advice I can give is not always to believe your first impression, you are looking at a three dimensional object with a two dimensional, indirect display. If you can find a way to verify your interpretation, whether it's by using a different angle or just looking at the area in question (e.g. the reverse side of the test object, if accessible).
Stick to it, UT still gives me a buzz and there is always something to learn. Products, materials and equipment evolve and you have to evolve with them.
Good Luck and don't give up, there is great satisfaction in beating a problem.
Dave

Re: where to begin in ut Ian, Good luck in your new venture (and remember, nothing ventured, nothing gained). I think that there are 3 areas where a bit of previous study prior to attendance on the course will help. If you are confident in these areas then you will be able to concentrate solely on the ultrasonic principles.

1. Very basic trigonometric functions, what i call the SOHCAHTOA memory-aid (if you dont know ask anyone reasonably proficent in maths). From this you'll be able to work out where those indications on your screen are coming from

2. Scientific notation, i.e. instead of 5000000 write 5x10 exp 6. This notation appears on most calculators and helps achieve the right answer when mixing very large and very small numbers (again ask the person in 1 above for help)

3. Manipulation of simple equations such as velocity = wavelength x frequency. You'll use this and a few other equations over the years to help select the right probe for the job.

Be confident in these 3 areas and you'll be able to concentrate fully onUT principles in that first week without struggling with fairly simple maths. And ask, ask, ask questions plus study at night so you can ask even more questions! My apologies if you are already proficient in these areas, i hope this might be of interest to others.

I'm working in the field of auto-ut (AUT) at present and there are plenty of guys working as operators with no prior ut experience so there is always an opening for you.
