The Welding inspection system ZLDS202AVIKScan Series is designed for non-contact measurement and quality control of welds.
Technical characteristics of the system can be changed for a specific task.
The scanner housing is made of anodized aluminum. The top panel of the housing has a touch screen display. On the underside of the housing there are two windows of the laser scanner, video camera and LED light. The power button is located on the front panel
of the housing.
The scanner comes with a special carriage equipped with a built-in incremental angle encoder. The position of the carriage wheels can be changed to measure corner welds.
The system includes the following main components:
·Laser Scanner
· Carriage
· Packing case
· Welding analysis software
Upgraded version will be available. It is a hand-held device, but it can be mounted on robot.
Scanning process control and visualization of results;
The software supports the construction of weld 3D model, welding analysis and reporting;
Measure the parameters of butt welds and corner welds(Equipped with a special bracket with built-in incremental Angle encoder, the position of the carriage wheel can be changed to measure fillet welds.);
Ready-made file of various types of welding;
Integrated laser sensor, camera, encoder in one;
Wi-Fi connection.

Operation of the scanner is based on the principle of optical triangulation.
Radiation of a semiconductor laser is formed by a lens in a line and projected to an object. Radiation scattered from the object is collected by the lens and directed to a two-dimensional CMOS image sensor. The image of object outline thus formed is analyzed by a FPGA and signal processor, which calculates the distance to the object (Z-coordinate) for each point of the set along the laser line on the object (X-coordinate). Scanners are characterized by the beginning of the range (SMR) for Z-coordinate, measuring range (MR) for Z-coordinate, measuring range for X-coordinate at the beginning of Z (Xsmr) and measuring range for X-coordinate at the end of Z (Xemr).
The device operates as follows.
The operator places the device above the weld to be measured, taps the start button on the touch screen display, and then smoothly moves the carriage with the scanner along the weld. The measurement results, synchronized with the carriage encoder, are displayed on the touch screen in real-time mode and transmitted wirelessly to the operator's PC for further detailed analysis and reporting.
