Ref : CND_TOFD1
DURATION :
07 DAYS

Objectives

Theoretical Part 50%
Practical Part 50%

Level 1 preparatory training for access to Level 2 certification according to EN ISO 9712

By the end of this training, the trainees will be able to:

  • Set the devices
  • Perform and monitor tests,
  • Record and rank results compared to written criteria
  • Attend level 02 in the different stages of control

Prerequisites

  • All persons in the manufacturing, control and maintenance departments wishing to prepare Level 2 certification according to EN ISO 9712
  • Control agents or inspectors responsible for manufacturing or monitoring welded fabrications in the following sectors: pressure vessels, welded constructions, railway, aeronautical and nuclear industries.

Teaching

Several Tools will be used in particular.

  • Slideshow and masterful approach to the transmission of knowledge
  • A Pedagogy by objectives is implemented.
  • Theoretical courses alternately with case studies, demonstrations and practical work on industrial control equipment, with parts representing real applications.
  • The training is led by specialized engineers and technicians of university rank, who are certified and experienced in theoretical and practical training.
  • TOFD equipment during training and certification session.

    • Program complies with the requirements of the NF EN ISO 9712 standard and the recommendations of COFREND.
    • The program can evolve and undergo changes according to the needs of the candidates and this after first evaluation of prospection of the group's knowledge.
