Flyer: shafTest system description

shafTest® shafTest® is a portable ultrasonic (UT) flaw detection system designed specifically to improve upon current UT techniques and equipment used to monitor the condition of large shafts and pins. Only a few highly skilled and experienced UT inspectors can confidently assess the structural integrity of a complex shaft by examining it in-situ from one end. The shafTest® system can verify the condition of a complex shaft without relying as heavily on individual operators skill and experience.

shafTest® Image shafTest® achieves this by reproducibly collecting a 3D ultrasonic signature of a shaft (V-scan), which can be stored for later retrieval and analysis. A cross-sectional view of the shaft at any depth provides a clear visual indication of the existence and extent of crack propagation. More importantly, cross-sectional data from different measurements can be directly compared and trended, with a graphical difference map indicating whether a crack has progressed between two measurements.

A-scan

shafTest® can operate in traditional A-scan flaw detector mode. All scan parameters are software selectable and are saved with data to a database for retrieval and analysis.

V-scan

V-Scan is a unique scanning mode where the end of the shaft is divided into a grid pattern. A camera and tracking software allows the grid position of the UT probe to be located. By storing A-scan information at each grid location a complete ultrasonic volume map is constructed.

This display highlights regions of interest (possible defects) and provides tools to plot an ultrasonic cross-section through the shaft at any depth by moving a slider along a simple schematic of the shaft.

By ensuring that V-scan data is always collected in a consistent and reproducible manor it is possible to plot the difference between cross section data collected from different measurements. In this way the progression of crack growth can be visualised graphically and monitored.

3D-Analysis

In addition to displaying cross-sectional data, tools are provided to quickly generate a 3D model of the shaft. The shaft can be viewed from any angle in order to visualise the relative size and location of defects within the shaft.
