Non Destructive test
(NDT).
To inspect or measure the
characteristics of a component, structure, material or an object without doing
harm. When the inspection or test is completed, the part can be still used.
Certification/Awarding Body:
Duration to completed the
course
2 weeks
4 types of NDT testing
1. Magnetic test
Suitable for:
This course is suitable for all NDT personnel, inspectors and technicians engaged in, or responsible for, inspection of castings, forgings or fabricated items during manufacture or in-service in different product sectors. It is also suitable for personnel working in the aerospace industry.
Course Content:
This course will teach you about the principles of magnetism, magnetic fields, induction, permeability and reluctance, and magnetisation. You will also learn about lines of force, methods of testing, interpretation of indications, demagnetisation, practical exercises, methods of assessing sensitivity, and instruction writing.
During the Level 2 instruction writing and application, attendees requiring only Level 1 training will carry out practical applications to written instructions.
Training is in accordance with the requirements of BS EN ISO 9712 and the course ends with the certification examination.
Course Objectives:
By the end of the course, you should be able to:
· Explain the basic principles of magnetic particle inspection methods
· Carry out magnetic particle inspection
· Write clear and concise inspection instructions and test reports
· Meet syllabus requirements for CSWIP, PCN Level 2
2. Penetrant test

3.
Ultrasonic
test
Suitable for:
This course is suitable for all personnel including testers, inspectors,
engineers and surveyors who require a thorough and comprehensive introduction
to ultrasonic testing of welded joints.
This course is also suitable for personnel working in the aerospace industry
and can be found under the Aerospace section.
If time is an issue, please consider our blended learning option -
study theory and concepts when and where you choose, then join the classroom
sesssions for hands-on practical.
Course Content:
Basic principles of sound; generation and detection of sound; behaviour of
sound in a material; the flaw detector; use of angled beam probes for weld
scanning; welding processes and weld defects; practical exercises on test
specimens containing simulated flaws; examination of parent plate, butt welds;
instruction writing. The course ends with the certification examination. Training
in accordance with the requirements of BS EN ISO 9712.
Course Objectives:
By the end of the course, you
should be able to:
·
Explain the theoretical background
of the techniques
·
Calibrate ultrasonic equipment
·
Measure the thickness of steel
plates and determine levels of attenuation
·

defects in typical welded butt joints
·
Interpret code requirements
·
Meet the syllabus requirements for
PCN/CSWIP Levels 1 and 2
4.
Radiography
test
Suitable for:
This course is designed for NDT
personnel, engineers, surveyors, inspectors, and quality engineers. The courses
delivered at TWI Cambridge are also available if you are working in the
aerospace industry.
Course Content:
This course will teach you about
welding processes and weld defects, properties of X- and gamma-rays,
sensitometry, film selection, film processing and spurious indications. You
will also learn about factors controlling contrast and definition, X- and
gamma-ray equipment, ionising radiation hazards, regulations, use of screens
and filters, selection of angle of aspect, image quality indicators, defect
depth location, castings, and reporting. You will receive training relevant to
the examination to be taken covering practical, inspection and theoretical
aspects as appropriate. The training is in accordance with the requirements of
BS EN ISO 9712 and ends with the certification examination.
