Is it for me?

This course is designed for you if you are an NDT operative, inspector or technician responsible for, or engaged in, the in-service application of eddy current techniques, writing techniques, and instructions for the inspection of ferritic welds.

What will I learn?

This course consists of one or two week courses and supporting PCN Level 1 and 2 examinations for eddy current inspection of weldments.

Traditionally, surface crack detection in ferritic steel welds with eddy current techniques has been difficult due to the change in material properties in the heat affected zone. These typically produce signals much larger than crack signals. Sophisticated probe design and construction, combined with modern electronic equipment, have largely overcome the traditional problems and now enable the advantages of eddy current techniques to be applied to in-service inspection of ferritic steel structures in the as-welded conditions. Specifically, the advantage of the technique is that under quantifiable conditions an inspection may now be carried out through corrosion protection systems. This means the costly removal and replacement of the protective coating is now not necessary.

When considering the use of eddy current techniques for coated welds there are a number of variables to assess prior to choosing specific pieces of equipment. These are as follows:

  • suitable eddy current probes/coils
  • material
  • coatings
  • weld geometry caused by the weld profile


The training is in accordance with the requirements of BS EN ISO 9712 and ends with the certification examination. 

What will I leave with?

By the end of the course, you should be able to:

  • Evaluate the variables defined above and define the limitations of examination
  • Write clear and concise inspection instructions and test reports
  • Meet the syllabus requirements of CSWIP/PCN Level 2

The course ends with the certification examination.

What else should I know?

There are no mandatory course entry requirements.

Price listed to direct access Level 2 and includes examination and levy fees. For Level 1 or training options, please contact Customer Services.

Please note:
All candidates attending a PCN examination (initial, retest or renewal) must provide photo ID (e.g driving licence number, passport number, PCN ID card) on the day of sitting the examination. Failure to do so will result in the candidate being turned away.

Training requirements:
The minimum required duration of training, which includes both theoretical and practical elements, is:

  • Level 1 - 40 hours
  • Level 2 - 40 hours (Direct Level 2 - 80 hours)

The training hours requirement is fulfilled when candidates attend one of TWI's training courses.

Certification requirements:
The minimum duration for experience prior to or following success in the qualification examination is:
  • Level 1 - 3 months
  • Level 2 - 9 months (Direct Level 2 - 12 months)

Certification will not be issued until successful completion of the examination and the required experience is achieved.
