EUROPEAN STEEL TECHNOLOGY AND APPLICATION DAYS 2017 - ESTAD 2017

Primetals Technologies has made an important Research & Development effort on laser welder field. The last step of its program was the evolution of its laser welder range by implementing the Solid state technology with laser cutting and welding. Since this step, twelve welders have been manufactured by Primetals Technologies. After more than six years of industrial feedback, the results are showing a high level of performance and reliability on process with a product weldability from Silicon steel to High Strength Steel with DP and TRIP grades and a constant cutting and welding quality. The operation enables a high reliability and optimized operator control, an optimum weld quality and geometry control and a perfect strip centering. Maintenance has also beneficiated from this technological evolution with a low maintenance level thanks to the use of optic fiber and Asolid Laser source and a preventive maintenance with the integrated Control Monitoring System. Some industrial results obtained in continuous processing lines recently installed in China will be exposed and highlights the related most interesting aspects for our customers.
