NDT examination centre

The qualification courses for Non-Destructive Testing (NDT) personnel are designed to train participants in every method and prepare them for the final examinations.

Metalprove is an Examination Centre qualified by Accredited Certification Bodies and carries out training courses that comply with the requirements of the EN ISO 9712:2022 standard “Qualification and certification of Non-Destructive Testing Personnel”, which is the most commonly recognized international reference in Europe, or with the Recommended Practice ASNT: SNT-TC-1A “Personnel Qualification and Certification in Non-Destructive Testing”, more requested in the ASME context.

Access requirements

To attend the courses there are no specific requirements, although a basic appropriate technical preparation and/or relevant professional background is desirable.

On the other hand, an adequate industrial experience is expressly required to access to the Qualification exams and achieve the Certification; this varies according to the testing method and the applicable regulatory framework.

If required, it is also possible to obtain a Certificate of Attendance issued at the end of the course.

Trainers

The course trainers are qualified and certified level 3 personnel, with many years of proven operating experience, in order to ensure practical approach to the training and be close to the needs of the participants. This is the basic difference with many other NDT training centres: Metalprove makes available its experience gained directly in the field.

Trainging Supports

The trainees are given a collection of handouts that take up and develop in more detail the concepts presented in the theoretical lessons.

During the practical training steel samples are used to understand and recognize the most typical defects in welding, casting and forging processes.

Locations and dates of the course

The course are held at the Metalprove headquarters, in an adequate classroom for theoretical training (desks, blackboard, projector, etc.), and using the laboratory equipment and premises for the practical part.

The program of the lessons is fixed by the didactic calendar.

Courses Offer and Program

Metalprove’s training offer for Non-Destructive Testing includes levels 1, 2 and 3 on all the main testing methods which are daily performed by the company at its customers: VT-PT-MT-RT-UT.

Level 1

A level 1 technician has the competence to carry out Non-Destructive Testing according to written instructions and under the supervision of level 2 and 3 personnel, id est:

Set up equipment;
Perform the tests;
Record and classify the results of the tests according to written criteria;
Report the results.

Conversely, Level 1 personnel shall neither be responsible for the choice of the test method or technique to be used, nor for the interpretation of test results.

Level 2

A level 2 individual has the competence to perform the following tasks:

Select the NDT technique for the testing method to be used;
Define the limitations of application of the testing method;
Translate codes, standards, specifications, and procedures into instructions adapted to the actual working conditions;
Set up and verify equipment settings;
Perform and supervise tests;
Interpret and evaluate results according to applicable standards, codes, specifications of procedures;
Carry out and supervise all tasks at or below Level 2;
Provide guidance for personnel at or below Level 2;
Report the test results.

Level 3

The Level 3 is the highest competence degree according to the qualification scheme of Non-Destructive Testing personnel; therefore, he/she must be able and demonstrate to:

Have the competence to evaluate and interpret results in terms of existing standards, codes, and specifications;
Have sufficient practical knowledge of applicable materials, fabrication, process, and product technology to select methods, establish techniques, and assist in establishing acceptance criteria where none are otherwise available;
Have a general familiarity with other NDT methods;
Assume full responsibility for a test facility or examination centre and staff;
Establish, review for editorial and technical correctness, and validate NDT instructions and procedures;
Interpret standards, codes, specifications, and procedures;
Designate the particular test methods, procedures and instructions to be used;
Carry out and supervise all tasks at all levels;
Provide guidance for personnel at all levels.

The topics provided for the various modules are dealt with more or less in detail according to the level to be achieved; it is possible to develop some specific topics that may be of greater interest to the participants.
