Weld beads in circular shapes are investigated by drawing linear cross-sectional lines on 2D data.

The project is described in detail. The difference between the highest and lowest points are measured after necessary post-process operations.

Flatness means Ebenheit in German. The difference between max and min points is calculated. Several different types of objects handled differently. PLC communication is established.

Three scanners are used to scan the top and side surfaces of the ingot. The flatness of the three surfaces is measured. This tutorial explains the project in detail. The calibration part is also very critical. It is one time only.

Measurement is actualized with Q4 QuellTech laser scanners. Several measurements are done to check the quality of the sculped ingot. The top surface and side surfaces are investigated.

The client would like to find the peak or pit position of the object. The program is developed in C++ with Qt. QuellTech Q5 scanner is used for this project.

Weld bead scanning and finding depth and width of the weld bead.

Robotized welding machines are getting more and more used by customers worldwide. The growing demand for increased Productivity, consistent quality is growing which makes Robot welding mandatory in many applications. However, in robot welding, there is a weld path programmed into the robot before welding, which then is used on all parts which have to be welded. Due to the tolerances of the parts, this path may vary from part to part. Another effect comes from thermal expansion of the weld material during welding, which leads to warping of the materials and therefore a new position of the weld seam.

QuellTech Q6 is used for this experiment. The number of the tubes and diameters of each tube is calculated using a 3D computer vision toolbox.

Transparent glue bead's height is measured. And to verify that the scanner is robust enough against transparent surfaces, a comparison on a surface with paper and without is paper made. It has observed that paper which is 100 micrometers is measured correctly. Therefore it has proven that transparent surface does not affect measurements in a negative way.

A transparent object is harder to scan since they have different optical properties. But this was a very successful scan with this very special scanner.

Air bubbles on a special chemical liquid wanted to be inspected by the client and client needed QuellTech laser scanners.

Battery manufacturers need measuring equipment for weld bead inspection for contacts. If weld beads are not constructed uniformly and symmetric then it results in increased current density over battery contacts and eventually overheating and severe harms to the system. To prevent this, donut shaped “Welding Beads” of battery contacts have to be checked with respect to several parameters: volume, center, radius, width, height parameters as well as the absence of defects in circular regions have to be verified. A Quelltech Laser Line Scanner is guided via a linear x-y axis over the weld beads acquiring a 3 D point cloud of these objects. A measurement software will compare these 3 D images against a tolerance channel and will determine pass or fail status. Failed parts are sorted out automatically.
