For over two decades, Eclipse Scientific’s BeamTool software has been widely used across the NDT industry for designing optimal Phased Array Ultrasonic Testing (PAUT) techniques. With the release of BeamTool 11, the software introduces more advanced tooling, enabling users to design more sophisticated PAUT inspection techniques. The new features include Sensitivity, Focal Area, and Resolution maps, for, which allow users to quickly assess how reflectors will appear in PAUT scans in terms of amplitude, shape, and size. For each focal metric, the software provides absolute minimum and maximum values, along with derived quantities such as vertical and horizontal resolution, enabling users to directly compare the influence of probe and wedge parameters. These tools empower users to quantify the relative benefits of multiple PAUT beamsets, select the optimal one, and estimate sizing accuracy for the finalized technique. Additionally, these metrics can be compared with those available for FMC/TFM techniques to determine if using FMC/TFM instead of PAUT offers significant advantages for a given inspection. This presentation will provide an in depth description of these focal metrics and show several practical examples where they can be used to choose the optimal technique parameters for real world inspection scenarios.
