In welding applications typically metallic pieces and components are joined together by melting the material in the connection area. In some applications, especially with thick materials, filler material is added to the joint. The heat is typically induced by electricity like in induction welding, spot welding and arc welding, or by electromagnetic radiation as in laser and electron beam welding. Due to the high energy impact on a small area, the processes emit large amount of thermal light. Therefore the core of the welding process is extremely bright, and thus also a major challenge for camera-based welding imaging systems.
Cavitar’s laser illumination enables clear visualization of welding processes as if they were essentially cold by eliminating welding brightness. This is mainly due to the high spectral brightness of the laser lighting in combination with efficient filtering of the thermal light. Our solutions can be applied principally in all arc and laser welding processes. The solutions range from high-speed imaging of welding for research purposes to quality assurance of welding processes in industrial production lines.
Laser Welding Imaging
- Live video of arc welding processes for quality assurance
- Clear image of the welding process
- Recognition of errors in real time such as weld misalignment
- Documentation of the process or desired parts of the process
- Ergonomic position to observe the process
- E.g. MIG, MAG, TIG, hybrid welding
- Recommended products: Cavitar’s Welding Camera
