What is a benefit of using 2D phased array probes compared to 1D probes?

Using 2D phased array probes offers greater flexibility in scanning profiles compared to 1D probes, which is a significant advantage in ultrasonic testing. A 2D probe can steer its beam in multiple directions due to its arrangement of elements across both dimensions, allowing operators to inspect complex geometries and obtain a wide range of angles from a single scan. This capability enables comprehensive coverage and better detection of defects that might be missed with more restricted scanning options provided by 1D probes.

The ability to customize beam angles and focus at various depths is particularly beneficial in applications such as weld inspections and detecting flaws in curved surfaces, leading to more reliable and efficient inspections. This flexibility not only improves defect detection but can also reduce the overall time spent on inspections, as fewer scans may be needed to cover the same area.
