Train Axle Inspection for Hollow Axles – The Boretest

Introducing the Boretest, Hollow Train Axle Inspection System. The Boretest is an ultrasonic NDT hollow train axle inspection system designed and manufactured by Tecnitest NDT, a leading European Advanced NDT Company.

Built to offer an easy and reliable solution for hollow train axle inspection, the Boretest is the ideal solution for in service inspections.  Transported on a fork-lift truck is easily manoeuvred between inspections.

train axle inspection systemThe Boretest is able to test the complete axle from just one side of the train with almost 100% of the axle being inspected in one pass. Actual inspection time is less than 30 mins.

This is carried out by utilizing different angular and zero degres ultrasonic probes to maximize the probability of detection.

The simple, user friendly set-up system negates the need to prepare complicated calibration set ups before each inspection.  As well as being easy-to-use the Boretest is versatile, allowing the testing of different types of axles within a range.

The Boretest records the results of every inspection, including the calibration, for further analysis, again highlighting the efficiency of the unit.

Characteristics of the system

Ultrasonic system

Utilizes 2 of the renowned 8 channel Socomate UT boards (using 5 channels from each board).

By utilizing different angular probes ,up to 10, to maximize the probability of detection, For each set of angled probes; one probe looks forwards and the other backwards.


The software is compatible with Windows 7, 8 or 10

Provides A, and C scan information giving real time positioning of defects.

Provides longitudinal and axial position of defects.

Stores all raw scan information for future analysis.


Replaceable probe head

Adjustable height of scanner

Scanning head is automatically pushed into bore in increments from 1mm (normally 4mm or 5mm) and rotates 360° after each incremental movement
