Metallurgy for NDT

5 Day Course (40 hours)

Course Description

Only Available On Request

This 40 hour seminar is a comprehensive source of the metallurgy necessary for use by personnel involved in designing, using, or evaluating nondestructive testing of aerospace products, materials and structures. The syllabus has been kept general in order to retain technical value but is broad enough to include all phases of the aerospace manufacturing industry and most of the materials used, together with information on in-service defects and their source.

The depth of training has intentionally been kept low so that airline and manufacturing NDT personnel, without a great amount of formal education, will develop understanding of the material. Ideally, participants will already have a knowledge of NDT. Wherever practical, mention and demonstration is made of NDT methods that might be suitable for the type of defect under consideration and their limitations.

This course is also suitable for students intending to take ASNT Level III or PCN Level 3 examinations as it covers the Materials and Processes portion of the Basic exam.
