Introduction to NDT Methods

A Three Day ‘Hands On’ Course

NDT is a cost effective and reliable technique in a wide range of applications which aids in the delivery of quality products and cost effective plant maintenance. Selecting the appropriate technique for a particular application requires care and understanding since all NDT techniques have limitations that must be well understood to ensure the desired reliability of inspections. Managers, Supervisors, Engineers and Technicians often have a requirement for the use of Non-Destructive Testing (NDT) techniques to maintain their plant & equipment.

To assist non NDT experts in understanding NDT, this Training course covers the basic theory of each technique, some of the many applications, relevant limitations and provides basic practical exercises to support the theory.

Engineers, Managers, Supervisors and Technicians seeking to obtain a better understanding of NDT and its role in industry would benefit from attending An Introduction to NDT Methods.

 

Course Content

An introduction to the basic theory and practice of the 5 main NDT methods and some newer technologies:

• Liquid Penetrant Testing (PT)

• Magnetic Particle Testing (MT)

• Ultrasonic Testing (UT)

• Radiographic Testing (RT)

• Eddy Current Testing (ET)

• Thermography

 

 

Day 1

 

The Role of NDT in Industry

NDT has an important role to play in the Quality Assurance, condition monitoring and maintenance programs of many organisations. A variety of typical examples will be examined and discussed, considering the importance that the correct NDT technique be selected and defect rejection/acceptance criteria be relevant to the material and its application. Quality Control is required to ensure reliable use of NDT techniques because failure can have devastating results. The standards that NDT providers need to meet are outlined.

 

Liquid Penetrant Testing

Liquid Penetrant may be the least costly and easiest technique to apply, however the inspection techniques require care to achieve reliable results, because not all defects are detectable using some methods and the dwell times normally used, particularly when temperatures are low. Both colour contrast and fluorescent techniques are covered.

Practical

Liquid Penetrant Testing is undertaken on a variety of welded, forged and cast specimens, using bulk liquids and aerosol packs.

 

Magnetic Particle Inspection

Magnetic Particle Inspection is only applicable to ferromagnetic materials, but it offers very high sensitivity in comparison with Liquid Penetrant techniques. It may be carried out by operators with limited training but an understanding of the techniques and equipment available will enable more effective inspection. Both black and fluorescent inks are covered using magnetic yokes, head, coil and threading bar on a bench.

 

Day 2

Magnetic Particle Inspection

Practical

 

Magnetic Particle Testing is undertaken using portable testing equipment, colour contrast and fluorescent magnetic particles. Guidance on interpretation of indications is given.

 

Thermography

A relatively new technology used in a wide range of applications from detection of termites to assessing the condition of switchboards, racehorses and aircraft structures. A brief introduction to the theory and some practical examples are covered.

 

Eddy Current Inspection Methods

Applicable to a wide range of inspections including metal sorting and crack detection. The operation of phase analysis systems is explained so that cracks can be found, sized and their depth determined.

 

Eddy Current Testing – Practical

Eddy Current Testing practice on film thickness, metal sorting, crack detection and conductivity measurements.

 

Day 3

Industrial Radiography

Industrial Radiography uses x-rays or gamma rays so both are covered. The significant limitations related to the orientation of the radiation, and the potential health hazards are covered in detail, as is the use of computed radiography. Examination of radiographs including welds and castings with a range of defects will highlight viewing condition and interpretation requirements.

 

Principles and Applications of Ultrasonics

Ultrasonics is a widely used NDT technique that may be applied to thickness testing, crack detection and weld inspection. Basic theory of longtitudinal and shear wave ultrasound behaviour in materials will be outlined and practical limitations explained.

 

Ultrasonics – Practical

The importance of trained operators cannot be understated. Students will be given the chance to carry out equipment calibration and simple inspections, including corrosion surveys and lamination sizing.

 

Assessment

There is no formal assessment conducted in the Introduction to NDT Methods course.
