Programmed, full-coverage ultrasonic scanning on complex geometry components — pressure vessel heads, nozzle welds, pipe elbows, turbine casings, and compound-curvature structural elements — with consistent probe contact, defined scan pitch, and automated coverage verification that manual scanning cannot deliver on curved and compound surfaces.
Automated robotic arm UT scanning
uses a multi-axis robotic manipulator to carry an ultrasonic probe — phased
array, TOFD, TFM/FMC, or conventional — across the surface of a component
following a pre-programmed path. The robot maintains controlled probe orientation
(normal incidence on curved surfaces), consistent contact pressure, and defined
scan pitch throughout — eliminating the probe angle variation, contact
inconsistency, and index pitch error that make manual scanning of curved
surfaces unreliable for critical flaw detection.
The scanning programme is defined
before inspection begins — scan path, index pitch, scan speed, and data
acquisition parameters are all specified and executed exactly. Coverage is
verified from actual encoder position data, not assumed from operator movement.
Every scan line is at the specified spacing. Every nominated inspection zone is
covered at the specified sensitivity.
