AVAILABILITY OF HUMAN RESOURCES FOR NDT CAREER TRAINING.

In the past students launching into a career of Non Destructive Testing came from a pool of apprentices, artisans and technicians. These people were technically minded and had no problem with NDT training.
This pool has since dried up.

Current trainees and students are drawn from whoever is available and chasing the money, therefore lack the technical quality and fall short of modern day demands of progressive NDT technology.

Despite ongoing recommendations during enrolments, some of these individuals and companies still launch straight into a Level II course - Results – low pass rates!

This situation tends to place an added burden on the lecturing staff. The lecturer has a full plate with knowledge transfer, bad habits and poor skills which have to be corrected and refined, therefore has no time to teach students technical basics. The training center has to meet the recommended minimum classroom and workshop qualification hours. Having said that, all the training centers in this country are presenting courses of at least double the minimum hours!

Brian Dadford


Trainees progressing through the recommended stages - commencing from Level I with practical experience - clearly show an above average pass rate once they sit a Level II exam

ANALYSIS

REGRESS IN THE CLASSROOM!
The root causes which inhibit successful knowledge transfer in the classroom and technical ability in the workshop have been identified:

Trainees and students enrolling come from various backgrounds and tend to regress classroom progress due to lack of basic practical mathematics, NDT technical knowledge, design drawing and use of basic English language as well as calculator operation.

This situation tends to frustrate more experienced and advanced students as there is no time to assist these students on a one to one basis in the class.

ADDRESSING THE CHALLENGE
A number of innovations have been presented:

Tuesday afternoons – the second day of the course - from 14.00h to 16.00h and a possible Wednesday as well, is a voluntary service offered by an independent Level III practitioner.
This service includes extra mathematics and terminology training and seems to be acceptable to the students and trainees who have responded positively.
Currently this service is available at no cost to the student, accept for time.

MODULES PRESENTED

  • BASIC PRACTICAL MATHEMATICS – This addresses the Law of Mathematics, rules of theorem and formulae in order to manipulate calculation when transposing symbols.
  • NDT TECHNOLOGICAL ENGLISH LANGUAGE TERMS – Ability to be able to interpret and apply understanding of test and examination questions.
  • DESIGN SKETCHING – Be able to present understandable outlines when depicting indication locality.
  • CALCULATOR MANIPULATION – Mastering the electronic calculator to expedite mathematical calculations.
  • HONING OF PERFORMANCE SKILLS – If time allows; to instruct and demonstrate correct approaches.

The author has attempted to address a developing trend where glaring lack of skills are apparent and how best to face and resolve this NDT scenario.

 

Levels of responsibility.

A Level I technician shall be able to:

  • Select the correct equipment as per the technique sheet.
  • Calibrate or test the conformance of equipment to the technique sheet.
  • Perform the inspection in accordance with the instructions.
  • Find the flaws.
  • Locate those flaws accurately.
  • Flaw sizing can be performed with MT & PT inspection methods.
  • Accept or reject test pieces when provided with such instructions.
  • Compile a report on those flaws with references and datum points.

A Level II technician shall be able to do all of the above and:

  • Compile a works instruction or technique sheet. Have it approved by Level III.
  • Select a NDT technique for a test method to be used.
  • Translate codes into technique sheet for actual working conditions.
  • Train and supervise trainees Level I’s & uncertified Level II’s
  • Perform and supervise inspections.
  • Compile training programs for trainees, Level I’s & Level II’s. Have it approved by Level III.
  • Compile exam papers for trainees Level I’s & Level II’s. Have it approved by Level III.
  • Perform flaw sizing.
  • Identify the flaws.
  • Accept responsibility for work done by a Level I’s & uncertified Level II’s while under his supervision.
 

Code of Ethics for Non-Destructive Testing Practitioners.

  1. Upon my honour, I swear that I shall hold in sacred trust the rights and faith conferred upon me as a NDT practitioner.
  2. As the safety and lives of others are dependent on my skill and judgement, I shall never knowingly subject others to risk which I would not willingly subject myself, nor those dear to me.
  3. In discharging this trust, I pledge myself never to undertake work, or approve work which I believe beyond the limit of my knowledge.
  4. Nor shall I allow any supervisor to persuade me to accept a work piece against my better judgement.
  5. Nor shall I permit my judgement to be influenced by any form of personal gain.
  6. Nor shall I accept a work piece about which I am in doubt, either as a result of an inspection performed by myself, or uncertainty in the ability of others.
  7. I realise the grave responsibility which is mine as a qualified and certified NDT practitioner to exercise my judgement on the acceptability of work pieces.
  8. I therefore pledge my unyielding adherence to those precepts of NDT for the dignity of my vocation.
 

REPORTING.

When writing a report the following must be remembered …

  1. A report of any kind is a legal document and must be able to be used in a court of law. Your method application, inspection areas and limitations - if any - should be clearly described. If it’s not on paper, it didn’t happen.
  2. You can be called to testify in a court of law on an inspection, at least 2 years after the inspection, even if you’ve changed employer. On critical inspections reports are stored for more than 10 years.
  3. No open spaces will be allowed.
  4. Your report will be used as reference by the next inspector that inspects that same piece. The aim is repeatability of inspections to monitor flaw growth.
  5. At level I you are allowed to complete a report & put your name to it, but not sign it.
  6. As a level II you may allow a level I to complete a report, but you put your name next to his and then sign it.
  7. On hand written reports you may not use correction fluid - "tippex". Corrections made on a hand written report should be deleted, initialled and then corrected. It is messy, but legal.
  8. Hand written reports shall be completed in black ink only.
  9. Drawings may be made in pencil but the labelling shall be in ink. A drawing or a picture is a very welcome addition to a report. It does wonders in court!
  10. Spelling does count in a legal document; get a dictionary!
  11. DO NOT use abbreviations unless you know for a fact that your client will be familiar with those abbreviations, or clarify.
  12. DO NOT SPECULATE ! Report only on what you find.
  13. The statement “No cracks found.” is NOT accepted by clients! You are not only looking for cracks, what about other flaws? Also, only if you’ve studied metallurgy or have lots of experience in the manufacturing and maintenance fields and you can say without a doubt that, whatever flaw indication you have found is indeed a crack, then go for it. For the rest of us, refer to it as a linear indication or even a crack-like indication. “No defects found.” When there are acceptance criteria or even, “no relevant indications found”.
  14. The statement “No defects found at time of test.” is NOT accepted by clients! Your report is dated anyway and you need to accept responsibility for your actions. Granted heat treatment, stress relieving and cyclic loads may cause flaws, fair enough; then state your results as; “no relevant indications found before heat treatment, or before shipment, or before commissioning.” “No defects found.” This is what clients pay for.
  15. Do the job in such a way that the client asks for you next time.
 

QUALIFICATION and CERTIFICATION.

NDT personnel, before they can perform an NDT task independently (without supervision), have to be qualified and certified competent in a particular NDT method by the employer.

This is how it’s done:

  • Firstly you have to have a high school education, with mathematics and science, and preferably technical drawings. You shouldn’t mind getting your hands dirty and there will probably be a lot of travelling involved. You also have to be medically fit: eye tests and blood cell count etc., for example when performing radiography. This is standard practice for all NDT methods.
  • Secondly you have to gain practical experience in the particular method. For example you are looking at UT and RT, it is recommended that you have at least three months of practical experience before attending the Level I course.
  • Then, after your Level I course, you have to have at least another three months of practical experience (for UT and RT) as a trainee before you may be certified as a Level I NDT Technician - You may now perform an NDT task independently. This period differs with each method of NDT.
  • You may attend a Level II course in a particular method once you and your employer feel you are ready to take up a supervisory position. You will be responsible for training and supervising other NDT personnel. You will also accept responsibility for the actions of Level I and uncertified Level II technicians.
  • But if you are going to be certified directly as a Level II inspector you will need at least nine month's practical experience as a trainee, under direct supervision of a certified Level II or III. Recommended for MT & PT only. This period differs with each method of NDT.
  • You may attend a Level III “refresher” course in the particular method once you feel you are ready to take up a managerial position. (you need more than 4 years of experience.) You will be responsible for training, supervising and certifying other NDT personnel. You will also accept responsibility for the actions of Level I and Level II technicians. You will analyse codes, write procedures, approve technique sheets etc.

The certificates:
Having successfully passed the general exam, which is attaining 70% for the exam, you will be issued with a certificate as proof of theoretical training. This certificate never expires, like your matric certificate.

THIS IS YOUR QUALIFICATION CERTIFICATE.
THIS CERTIFICATE DOES NOT GIVE YOU THE RIGHT TO CARRY OUT AN NDT INSPECTION INDEPENDENTLY. YOU ARE STILL A TRAINEE UNTIL THE COMPANY CERTIFIES YOU COMPETENT TO DO THE JOB.

Now for certification of competency or authority to SNT - TC - 1A, you will write three exams.

The GENERAL (qualification exam as above), SPECIFIC and a PRACTICAL exam, a pass mark of 70% is required in each aspect, BUT before you can be certified you need your general, specific and practical exams to make up a composite mark of no less than 80% aggregate. (Gen% + Spec% + Pract% ÷ 3 = more than 80%)

You also need the necessary on the job training and practical experience as deemed necessary by the company – your employer - and the company's Level III, in accordance with the company's Written Practice.

This written practice covers the qualification and certification of NDE personnel employed by the company. It is drawn up by the company and approved by the company's Level III or an appointed Level III from an outside agency.

  • Remember you must retain your hours of experience if you wish to be certified and the best way to do this is to log your experience in an appropriate log book which should be verified by your supervisor on a regular basis.
  • This log book is virtually your NDT CV and should be at hand at all times in the advent that your experience needs to be verified by a Level III or the client.
  • In order for the employer to certify you competent to do the job independently he must ensure the following documentation is in place and available on file.
  • Educational background.
  • Proof of course training in the applicable method.
  • Practical experience.
  • Examination results, i.e. General, Specific and Practical.
  • Physical capability, e.g. near vision accuracy and colour perception.

The completed certification document must be signed by the company representative and endorsed by the appointed Level III in order for the document to be valid.

Certification remains valid for a period of five years and terminates when you leave the company. Recertification for the company will be by examination i.e. General, Specific and Practical. Depending how this is stated in the company’s written practice.

However, should you remain with the same company recertification for another five years can be done on the basis of continued satisfactory performance, without examination.
Of course this all depends on the how it is laid down in the company's written practice.

Should you have any questions in this regard, please do not hesitate to ask your instructor for assistance.
