Thick Strip Cutting and Welding With High-Power Solid-State Laser Technology Breakthrough

摘要

The extension of proven Primetals Technologies thin strip laser cutting and welding concept to thicker strips has been reached by Primetals Technologies thanks to adaptation of high power solid state laser. Through the development of a dedicated high performance laser cutting head, the comprehensive analysis and optimization of cutting and welding processes, and ultimately the construction of a scale 1:1 pilot machine, qualification tests have been carried out to confirm the capability of such disruptive solution. The major breakthrough on high speed laser cutting leads not only to optimum quantity levels, but also to higher robustness with significantly less sensitivity to incoming material variations and clearly pave the ground for alternatives to mechanical-cut based solutions.
