Revealing the secrets of the welding process ACHIEVING high image quality in the visualisation of welding is a formidable challenge due to the powerful radiation generated by the process. To overcome this challenge, Cavitar Ltd has developed a welding monitoring solution based on pulsed high power diode laser illumination. High quality images from the core of the welding process provide valuable information for scientific and industrial R&D purposes. This information can be utilised for process development and optimisation as well as for troubleshooting. High quality video of welding is also powerful tool in educational and training purposes. High quality images also enable reliable and accurate online image processing. In addition to seam tracking, features such

The new X-RAY 6000 SIKORA has made more advances with its X-ray technology. Thanks to a technological fine tuning SIKORA launches the second generation of the X-RAY 2000, the new X-RAY 6000-series for the measurement of the eccentricity, wall thickness, ovality and the diameter in hose and tube extrusion lines. For example, innovations have been made with the XLL-X-Ray tubes (eXtra Long Life) as well as a selectable measuring rate. Additionally, the X-RAY 6000 offers precise measurements even under difficult climate conditions. The measuring values are displayed at the processor system ECOCONTROL 6000 on a 15" or 19" TFT monitor. In combination with the display and control device, the new dual and triple-axis measuring systems ensure an optimum process control in automatic mode.

as keyhole and melt pool properties can be analysed. Numerical process data can be utilised for documentation, alarm or process control purposes. The Cavilux welding monitoring solution consists of combined illumination and camera system with other necessary components. The volume of the monitor unit (camera + illumination) can be less than 1dm 3 and the weight less than 200g. The solution can be applied in arc, laser and hybrid welding processes. The monochromatic nature of laser light enables efficient filtering of thermal light. In addition, the use of short high power light pulses accurately synchronised with camera exposure time of similar duration further suppresses the effect of thermal light. As a result, high quality images showing both hot and cold regions simultaneously obtained. Cavitar Ltd’s welding monitoring systems can provide high quality images and videos for both real time and high speed applications. For more information, please contact Cavitar Ltd.
