NDT Inspection

Just by knowing the block size and sequences you can not do UT.

You better undergo training as per ASNT.TC. 1A Level II in Ultrasonic Testing Methods to understand the procedure, selection of straight and angular probes, types of flaws and its detection, measuring thickness etc. and without proper training you will never be successful in your attempts.

It will take minimum 40 working hours to completer the course. After successful completion of the course and certification you will also become a professional and do the testing on your own.

Otherwise , Please employ a professional in the field to do it on your behalf and submit the results to you.

Hello sir, I have been trained theorithically for 48hours on UT but practically zero, the so test pice is for my personal I.e for me to pracvtice with so I,m trying to apply my theoritical knowledge but it has not been easy. Thank u BELOW is the specification It is a newly welded plain carbon steel tank and I wish to inspect the wellds for defects like porosity, slag, lack of fusion and incomplete penetration The plate in question is flat and uniform in thickness

No NDT Level II course is complete without practical. Let it be RT, PT, MT UT etc.

All courses has a practical Question paper along with General and Specific and one has to score an aggregate of 80% for all the 3 papers.

Hence it is surprising to note that, they did not teach you practical in UT.

Expertise comes at a later stage and with experience but, to initiate the inspection practical is important and please learn it at any institute where they teach properly.

Above details are mentioned to give an idea to you and not find fault with the institute where you underwent the course.

If it is strictly a steel "Plate," and of uniform thickness, you can get away with straight through transmission with a thickness UT unit. That will give you some useful information. However, if it is a large piece, then the services of a professional is required for a more thorough and competent inspection. I agree that taking a course in UT will help, but not in the short term for your needs. UT is a very specialized inspection that requires much training and experience. Good luck.

Posts 1&2 are headed the right direction, but fail to mention that you have not even BEGUN to provide sufficient data in order to obtain the most thorough and correct response.

You state: "I want to inspect a 32mm carbon steel plate" ... without clarifying:

Is this new or in-service? Are you simply interested in a "Thickness/Lamination Scan" seeking any corrosion on the backside or laminations within? Or, is it welded, and you wish to inspect the weld for defects? If so, is it NEWLY welded, and you are seeking flaws such as porosity and slag, lack of fusion, insufficient penetration, etc etc, OR, is it in-service and you are only concerned with fatigue-related defects (cracking)...?

What is your Critical Defect Size? (Makes a big difference, insofar as probe selection!)

If it is newly welded, is this an article that is subject to any Code requirements? If so, then the Code will give numerous guidelines to assist in heading the right way.

Is the plate flat or curved? The math will be different when it comes to interpretation of echo responses.

G.I.G.O.

Lots more detail, please, before people start going off the deep end answering way out-of-bounds for your particular needs.

Best Wishes ~
