ML-69B Series - 2000 W - 5000 W Fiber Laser Welder
The ML-69 B Series are high-power fiber laser welders with a maximum output of 5 kW. High power laser enables welding of even thick plates at a high speed.
One compact, proven industrial package with the Miyachi worldwide support makes it an ideal production tool. The integrated back reflection measurement safeguard the laser in all circumstances against damage due to back reflection.
The good beam quality of the fiber lasers coupled with high CW (Continuous Wave) powers offers deep penetration welding at high speeds. These fiber lasers replace not only traditional CO2 laser and Disk lasers, but also MIG, TIG and electron beam welding.
The ML-69 B Series have the advantage of excellent laser oscillation efficiency, energy saving and low cost of ownership, resulting in contributing to environmentallyfriendly manufacturing. The integrated power measurement and active regulation provides exceptional stability of the pulse energy (typical <0,5% pulse to pulse).
The ML-69 B Series performs high-speed CW welding and welding of precision metal plates. Typical applications are welding of electronic components, automotive parts, mechanical parts, plastic parts, medical equipment and precision sheet metals; sealing of minute parts; fine spot welding; high-speed seam welding; thick plate welding; etc.
