Technical specification

Communication, steering and control mode

Data acquisition and co-ordinate frame of reference

• 72 images collected automatically with full overlap between images to ensure no missing regions

• File name is entered by the user and saved in the project directory

• Coordinate frame of reference options (i.e., ZERO degrees for camera and laser data) options:

  • Top-dead-centre (based off gravity)

  • Bottom-dead-centre (based off gravity)

  • Visual point of interest (using live camera image)

Control software live view

Laser calibration and verification

Live feed of the laser data as well as either the side (weld camera) images or the front camera images. Note that the front camera may not be present in some configurations.

Lighting can be enabled/disabled in the software. The image brightness can be adjusted by reducing or increasing the camera exposure time via the control software.

The current head angle is also shown in the live view.

All lasers are supplied with calibration certificates traceable to UKAS and International Standards.

On-site verification of the laser is carried out using calibrated ceramic step gauges.

Typical project validation involves scanning project welds during the welder qualification stage and logging of scans and defects into a project defect library. In instances where the quantitative laser values need to be validated the weld is typically macro sectioned and the results compared to the IVLT results. In some instances, repeatability testing is carried out whereby the same weld is scanning multiple times (i.e. ten (10) times) and the deviation across these ten (10) scans analysed.

NOTE: We have successfully conducted several of these validation campaigns for customers and it is not always stipulated within the contract. Typically it is only required for new customers or for particularly high-profile projects.

Full-resolution data is viewable after the scan within the WeldAnalysis software. At this stage there will also be more viewing options available to visualise the data. They are represented by icons on the left menu. The user will see two (2) views at a time and can change which the current views are at any point. Left-click on the selected icon to use this view on the left side, and right-click on another icon to use on the right of the screen. If a view is already in use on the other side the two (2) views will switch places. The four (4) views available, left to right are:

• Graph view: This view represents the current profile on a graph and quantifies the scale of the profile. Use the bottom scrollbar or arrow keys to browse the profiles

• 3D middle view: This will represent an area of the weld as a 3D topographical map viewed from above and at an angle. This gives an idea of the shape of the weld

• Photo view: This view displays the photo collected closest to the current position. The photo will update as the user scrolls around weld

• Image view: This view represents using a scale of shade of blue. Here the weld is usually visible, along with darker areas of concavity, lighter areas where high root penetration exists, and contrast between left and right indicating greater HiLo

Re-entrant angle is available to view within the WeldAnalysis user interface. This is a useful parameter when steepness of the weld is of interest.

Before generating the report, the user can use multiple views, alongside plots of measurement statistics to carry out a closer inspection of any features, and record comments before the report is created. The icons on the bottom left side of the screen which appear allow the user to view the analysis of the inspection category. Hover over each icon in the left menu for a description of what each is. The graphs will display the tolerances/bands set in settings, marked on the graphs as lines and outlined underneath under the heading Statistics. Under Statistics, it will also detail the max. and min. values and their corresponding angle.
