infrared), optics and filtering. Everything is packaged into highly compact and robust sensors that are designed for challenging industrial environments and are easy to integrate into production lines and in some configurations even into hand welding equipment. As an example, it is possible to monitor welding behind a corner, in severely limited space (eg inside a tube) or in dangerous environments not accessible for people (eg nuclear plants). CAVILUX Welding monitoring technology is equally applicable for arc, laser or hybrid welding processes and can be utilised in production, research and development or training. The main benefits in production result from the fact that defects can be detected and corrected without delay, thus increasing yield as well as improving quality and reliability. In addition, the operator can monitor the process easily and safely. Benefits in research and development include faster process optimisation and better understanding of the process. The equipment is also valuable for training purposes because the welder can immediately see the quality of the weld and adjust accordingly. Several models of CAVILUX Welding monitoring solutions (Standard, Mini and HiRes) are available for different needs. Depending on the configuration (laser wavelength, laser power, laser pulse duration, repetition rate and optics) the laser class is typically 2M, 3R or 3B. Therefore eye-safe solutions are often possible. Also customised solutions and high-speed systems are possible. For more details, please visit www.cavitar.com
