Long Seam weld Inspection with Phased Array
Phased Array inspection of curved parts brings some real technical challenges.
Evaluation of seam welds on small diameter and heavy wall pipes is difficult to accomplish using actual tools that, most of the time, are based on a flat surface model. This often leads to erroneous and imprecise flaw location and sizes.
This Application Note presents a totally new approach of inspecting seam welds and more generally curved parts. The novel method rethinks almost all aspects of the traditional implementation. Starting from an original focalisation of beams that allows the technician to define specific resolution of focal points in a zone of interest.
