One of the biggest issues with performing Phased Array and ToFD Weld and corrosion scanning is the high cost of scanner hardware. This leads to most companies having only 1 scanner that needs to be rebuilt frequently and therefore is exposed to wear and tear. Further most of the common scanner hardware is limited in their useability. I have more than 10 years of PAUT field experience and have developed a practical and versatile 3D printed series of scanner components that can be applied to different component and weld configurations. Our concept is not to compete with much more expensive scanners, the idea is to be able to have 2, 3 or 4 scanners setup for the jobs you need to do instead of having to rebuild that one scanner you have. I have designed the scanners so that the magnetic wheels and the encoder runs almost in-line with the wedges, where there is good contact and clean surfaces.
