The FMC Calibration Block is specifically engineered for use with Full Matrix Capture (FMC) and Total Focusing Method (TFM) — advanced ultrasonic techniques that deliver highly detailed imaging for precise defect characterization and sizing.
FMC is a data acquisition process that captures a complete matrix of ultrasonic signals for later processing, while TFM uses this data to focus the ultrasonic image at every point in the inspection zone, delivering optimal resolution across the entire view. This block helps operators establish primary reference responses for FMC/TFM-enabled systems, ensuring accurate and repeatable inspections where defect sizing is critical.
Compliance: Manufactured to ASME Sec V, 2019 specifications for FMC/TFM calibration.
Realistic Finish: Media-blasted to mimic real component conditions — no polished scanning surfaces.
Flexible Size: Standard size 7.5″ wide × 11.5″ long, thickness 0–1″ (customized as needed), covering weld thicknesses ±25% of block thickness.
