An Introduction to Non-Destructive Testing Methods

A Three Day ‘Hands On’ Course presented by

Dr Gary Martin MIEAust CPEng

NDT is a cost effective and reliable technique in awide range of applications and it aids in the delivery of quality products andcost effective plant maintenance. Selecting the appropriate technique for aparticular application requires care and understanding since all NDT techniqueshave limitations that must be well understood to ensure the desired reliabilityof inspections. Managers, Supervisors, Engineers and Technicians often have arequirement for the use of Non-Destructive Testing (NDT) techniques to maintaintheir plant & equipment. To assist non-NDT experts in understanding NDT,this Training course covers the basic theory of each technique, some of themany applications, relevant limitations and provides basic practical exercisesto support the theory. Engineers, Managers, Supervisors and Technicians seekingto obtain a better understanding of NDT and its role in industry would benefitfrom attending An Introduction to NDT Methods!

An Introduction To NDT Methods

Course Content

Day 1

A Basic Introduction to NDT

An introduction to the basic theory and practice ofthe 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);

• Alternating current field measurement and;

• Thermography.

The Role of NDT in Industry

NDT has an important role to play in the QualityAssurance, condition monitoring and maintenance programs of many organizations.A variety of typical examples will be examined and discussed, considering theimportance that the correct NDT technique be selected and defect rejection/acceptancecriteria are relevant to the material and its application. Quality Control isrequired to ensure reliable use of NDT techniques because failure can havedevastating results. The standards that NDT providers need to meet areoutlined.

Liquid Penetrant Testing

Liquid Penetrant may be the least costly and easiesttechnique to apply, however the inspection techniques require care to achievereliable results, because not all defects are detectable using some methods andthe dwell times normally used, particularly when temperatures are low. Bothcolor contrast and fluorescent techniques are covered.

Liquid Penetrant Testing – Practical

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

Magnetic Particle Inspection

Magnetic Particle Inspection is only applicable toferromagnetic materials, but it offers very high

Sensitivity in comparison with Liquid Penetranttechniques. Operators with limited training but an understanding of thetechniques may carry it out and equipment available will enable more effectiveinspection. 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 portabletesting equipment, color contrast and fluorescent magnetic particles. Guidanceon interpretation of indications is given.

Thermography

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

Eddy Current Inspection Methods

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

Eddy Current Testing – Practical

Eddy Current Testing practice on film thickness, metalsorting, crack detection and conductivity

measurements.

Day 3

Industrial Radiography

Industrial Radiography uses x-rays or gamma rays soboth are covered. The significant limitations related to the orientation of theradiation, and the potential health hazards are covered in detail, as is theuse of computed radiography. Examination of radiographs including welds andcastings with a range of defects will highlight viewing condition andinterpretation requirements.

Principles and Applications of Ultrasonics

Ultrasonics is a widely used NDT technique that may beapplied to thickness testing, crack detection and weld inspection. Basic theoryof longitudinal and shear wave ultrasound behavior in materials will beoutlined and practical limitations explained.

Ultrasonics – Practical

The importance of trained operators cannot beunderstated. Students will be given the chance to carry out equipmentcalibration and simple inspections, including corrosion surveys and laminationsizing.

Assessment

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

Who Should Attend

The Introduction to NDT Methods Training Course isrecommended for:

• Engineers;

• Managers;

• Supervisors;

• Quality Manager;

• Condition Monitoring Technicians;

• Engineering Technicians; and

• Any non-technical (NDT) person responsible for NDTTechnicians or ordering NDT techniques to maintain plant & equipment, andequipment available will enable more effective inspection. Both black andfluorescent inks are covered using magnetic yokes, head, coil and threading baron a bench.
