It must have been around 2008 when I first discovered GWT in the field of non-destructive testing (NDT), and I was quite intimidated by the complexity the subject was showing firsthand. As an experienced ultrasonic testing (UT) operator from the ‘90s, I had trouble understanding parts of the physics, particularly the behaviour of the different waveforms, as guided wave testing does not really compare to traditional UT. I saw a variety of companies starting to develop inspection systems based on different transducer techniques, and in most cases the results were astonishing. However, the pioneering led to some failed initiatives as well. Read to learn more.

I was first drawn to guided wave testing when I was closely involved in developing a short-range guided wave tomography system in 2012. During that period, I learned much about guided waves and the technique's potential. Last year I completed the CSWIP L1 guided wave training course. This was an excellent opportunity for me to deepen my GWT knowledge to better assist potential users. We used Eddyfi Technologies’ older generation Focus+ system and the Piezo-type collars during training. The training went great, and towards the end I felt confident in my skills to operate the equipment. You really had to pay close attention to what you are doing when collecting data and during analysis.

Half a year later, Eddyfi Technologies launched Sonyks and I had the opportunity to test out the most advanced guided wave ultrasonic testing instrument! The system is the successor of the Teletest Focus+ system and has been completely redesigned, packing unprecedented new features and capabilities.
