Introduction

Conventional methods of non-destructive testing (NDT) are used in a variety of industry sectors, including everything from oil and gas, renewables, rail, construction and fabrication, shipbuilding, steel production, biochemical through to theme parks and fairgrounds.

The methods used for conventional NDT include visual testing, penetrant testing, magnetic testing, ultrasonic testing, radiographic testing and eddy current testing, but all share common features in that the materials under test are not harmed in any way. These methods are well established and widely applied.

Our training courses will provide you with the skills and certification to enter into the world of NDT, additionally, we also offer eLearning for courses such as ultrasonic testing to supplement your classroom-based studies via our Virtual Academy. With so many opportunities available in conventional NDT, our suite of courses could open up an abundance of career opportunities for you.

How can I verify the required industrial experience?

Industrial application of the NDT method is a requirement before certification can be awarded. If you are working for a company using the method, it is a case of logging this experience and having this verified by your supervisor or if you are working on a contract as self-employed it can be signed by the contract client (Note: NDT certification schemes often require that the person verifying your experience holds the same NDT method and level of qualification themselves).

The experience duration needs to match the minimum requirements as detailed by the certification scheme documents, these can be found on the scheme websites (e.g. CSWIP or BINDT).

Can I come and sit on the course without any industrial experience?

Yes, for those not working for a company or on a contract that is using the NDT method a 2-year period is normally given after the examination date to send your experience verification to the scheme body. For further advice please do not hesitate to contact us, however, this applies only to levels 1 and 2.

What are the best courses to start with?

We normally advise candidates to start with a surface inspection such as penetrant testing (PT) or magnetic particle testing (MT), however if a candidate already has NDT experience in another method, we would perhaps suggest sitting the course in that particular method. Generally, you should aim to achieve at least 2 surface inspection methods and what we call a volumetric inspection method, such as radiography or ultrasonic testing.

Can I use my welding inspector experience for NDT?

Unfortunately any experience claimed must be in the same NDT discipline, however, for visual testing (VT) a welding inspection certificate may contribute towards the EN ISO 9712 visual testing (VT) experience requirement for the welds sector.
