Phased Array Y joint lack of fusion

Hi,
Just clarifying, from what I understand for good detection of lack of fusion defects, the beam should be entering perpendicular to the crack. However, the typical toe of a Y joint has very little beveling and is almost 0 degree. So for a phased array used in the toe region, the highest chance of detecting a lack of fusion weld is probably the 70 degree region?( closest to 90).

Is my understanding correct?

nresolved asset integrity problem in the industry. Current methods for measuring wall thickness with liftoff, without removing insulation, all have severe limitations. Eddyfi introduces Lyft — a reinvented, high-performance pulsed eddy current (PEC) solution. The patent- pending system features a state-of-the-art portable instrument, real- time C-scan imaging, fast data acquisition with grid-mapping and dynamic scanning modes, and flexibility with long cables. It can also scan through thick metal and insulation, as well as aluminum, stainless steel, and galvanized steel weather jackets. Who else but Eddyfi to reinvent an eddy current technique and redefine CUI programs. Got Lyft?
