At the upcoming EMO exhibition in Milan (21st to 28th October) the Rofin Laser Macro group will launch its new top-of-the-line CO2 laser, the DC 060 W.
At the upcoming EMO exhibition in Milan (21st to 28th October) the Rofin Laser Macro group will launch its new top-of-the-line CO2 laser, the DC 060 W.
The diffusion-cooled new power class model now delivers an average output power of 6kW, and is mainly designed for welding applications.
The laser is ideally suited for welding tasks requiring considerable weld depth or involving a long focal distance (ie large scale remote welding).
Thanks to its excellent beam quality of K x 0.9, extremely narrow seams with minimal heat distortion can be obtained, as required in the welding of gear parts.
The superior beam quality generates a higher power density that can be converted into higher processing speeds.
For applications where the near Gaussian mode properties are not necessary but increased welding seam widths are required, the Rofin DC 060 W is also available with a "donut-mode" to provide increased welding seam widths.
Special internal optics increase the focus diameter of the laser beam at a given focal distance by a factor of two.
The result is an extremely reliable welding process even for parts with large tolerances.
Despite higher output power, the footprint of the diffusion-cooled DC 60 W remains the same as its the DC050, its 5kW sister, making it the most compact laser in this power class.
As with all CO2 slab lasers, the DC 060 W requires no gas circulation and its single transmitting lens is a diamond window.
Gas changes are only required every 72h, resulting in extremely low gas consumption and nearly maintenance free, service friendly operation.
Main application fields for these lasers are ultra-large-scale remote welding of car body parts in the automotive industry, welding of aluminium parts or welding of tubes and profiles.
Rofin will also highlight tube and profile welding during EMO by displaying the DC 060 together with Rofin's PWS profile welding system.
This complete beam delivery system with an integrated process control for gap recognition and seam tracking guarantees highly reliable weld joints.
The system offers either tactile or noncontact (feedback) welding options, and is programmable to allow additional customised output functions, such as control of laser power or regulation of the process gas.
The PWS achieves a positional accuracy of up to 20um at a production speed of up to 30m/min.
Integration into existing processes is easily achieved, and further customer specific requirements, such as logging process data for quality control, can be implemented.
Via a clear and movable control panel, which is mounted on a bracket, laser parameters and functions as well as seam tracking on the work pieces can be easily controlled and optimised.
