Course Description

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.

Course Description

The Workshop covers Refresher Training for individuals wishing to take:

• Employer Based recertification examinations at Level II
• Corporate Employer Based examinations or ASNT Central Certification examinations at Level III
• PCN Examinations at Level 3

Course Content

Subjects covered are:

• Penetrant
• Magnetic Particle
• Eddy Current
• Ultrasonic
• Radiography
• Visual

For the ASNT Level III Basic:

• The Documents SNT-TC-1A, ANSI/ASNT CP189 and Code of Ethics
• Materials and processes
• An overview of all methods, including:
  Thermal/Infra-red
  Leak Detection
  Neutron Radiography
  Acoustic Emission

For the PCN Level 3 Basic and Part C3:

• The Document PCN
• General Materials and processes
• Overview of the NDT methods for PCN Basic Part B
• Procedure Writing and key processes

Subjects may be reviewed in an order mutually agreeable to the participant and the instructor for the Workshop.

Participants are grouped by NDT Method and work at their own pace doing practice examinations under the constant supervision of a Level III (3) instructor. Student problems are addressed as they occur.

Learning Objectives

1. The objective of the Level II Workshop is to optimise preparation of the participant for employer based re-certification examinations at Level II by identification of weaknesses.
2. Although we may recommend the number of days according to the method, our aim is to meet the requirements of the individual participant.
3. The objective of the Level III (3) Workshop is to prepare the participant for Employed Based Corporate Level III, ASNT Level III, and PCN Level 3 examinations or renewals by concentration of work in weak areas. Again we may recommend the number of days according to the method and type of examination being taken, but our aim is to meet the requirements of the individual participant.
4. The Level III Workshop is for Level II inspectors who meet the experience requirements to take Level III examinations.
5. It is stressed that this is a refresher course and should additional training be required prior to Level III examinations, it is recommended that the participant attend all or part of the Level II courses detailed in this brochure.

Course Description
