Contacts WHAT IS NON DESTRUCTIVE TESTING (NDT)? Non-Destructive Testing or NDT , also called Non-Destructive Testing, brings together all the processes and techniques that provide information on the integrity and health of a material or part without altering or destroying it. NDT is to materials what medical imaging is to the human body. NDT APPLICATIONS All industrial sectors use NDT: aeronautics, aerospace, nuclear, petrochemicals, railways, automobiles, metallurgy, foundry, etc. on parts important for the safety of an equipment or installation. NDT must allow the identification of all faults likely to alter the availability, safety of use and / or more generally the conformity of a part for the use for which it is intended. NDT is applied to forgings, rolls, cast welds, etc. in three cases: the inspection during manufacture , which generally results in the sorting of defective parts inspection on receipt of a part or installation to detect, define the nature and characterize the faults in-service testing to detect, define and size faults that appear during their lifetime and monitor their development over time TYPES OF DEFECTS SOUGHT We are looking for two types of faults: the surface defects such as cracks, holes, cracks, pitting ... the internal defects such as porosities, blowholes, inclusions, cracks not emerging, variations in thickness due to wear or corrosion ... THE PROCEDURES L’utilisation des procédés de CND suit des procédures qui garantissent l’objectivité, la reproductibilité et la fiabilité des techniques, des procédés. Ces procédures sont basées sur des normes (en général CEN ou ISO), des codes et des spécifications propres à certains industriels. LA CERTIFICATION DU PERSONNEL DE CONTRÔLE En France, le niveau de connaissance et les compétences du personnel sont garanties par une certification délivrée, sur la base d'examens théoriques et pratiques, par la COFREND, Confédération Française des Essais Non Destructifs. 13 000 certifiés en France. LES MÉTHODES DE CND The main methods of NDT are: visual examination, penetrant testing, magnetic particle testing, eddy currents, ultrasound and radiography.
