Used Flaw Detector in Wisconsin, USA

Overview

Flaw detectors are portable instruments used in non-destructive testing to locate cracks, voids, inclusions and other discontinuities in metals, composites and welds. Common methods include ultrasonic testing (UT), eddy current, and magnetic particle inspection; each detector is tailored for sensitivity, probe type and signal processing. These units are essential for quality control, repair verification and safety inspections across fabrication, oil & gas, aerospace and maintenance operations.

FAQ

What should I check when buying a used flaw detector?

Verify the inspection method (UT, eddy current, etc.), probe compatibility, calibration records, firmware version, battery condition and any physical damage. Confirm available accessories like transducers, couplants and reference blocks.

How should a flaw detector be shipped to avoid damage?

Ship in the original hard case or a custom padded case with probes removed and secured. Include desiccant for humidity control, lock batteries if required, and use insured freight with tracked, vibration-minimizing packaging.

What maintenance and calibration schedule is recommended?

Follow manufacturer intervals: perform functional checks before each use, annual calibration traceable to standards, periodic probe checks and software updates. Keep records of calibrations and replace consumables like probe cables as needed.
