Emden/Leer University of Applied Sciences offers consulting and feasibility studies for laser-based manufacturing in the areas of cutting, joining, surface layer processing (hardening, marking), and additive manufacturing.

To accommodate a wide range of applications and manufacturing processes, various laser systems with different properties, such as maximum laser power and laser wavelength, are available. Depending on their application, the laser systems are deployed on gantry or robotic systems. Additional equipment also enables laser welding with filler wire, as well as hybrid applications in conjunction with TIG or MSG welding processes.

The qualification of work results can be carried out quickly in the materials science laboratory. In addition to material-technical investigations, a high-speed camera can also be used to understand process dynamics. This is particularly relevant in the field of welding technology and melt pool dynamics.

This allows, for example, application tests to be carried out to select the right combination of laser type and material, and to determine the required laser power for laser applications, independent of the manufacturer, for investment decisions.

equipment

The laser cell is the newest component of the laser material processing laboratory:

• A high-power hybrid laser (   LaserLine LDF series  ) with a laser power of 4000 watts when operated as a diode laser and 2400 watts when operated as a fiber laser, enable the processing of a wide variety of materials.

• Various interchangeable working heads and optics for different manufacturing tasks from the processing areas o Separating o Joining o Generating (deposition welding) o Changing material properties (hardening)

• Processes can be optimized through integrated control systems, such as distance control during laser cutting or temperature control during hardening/joining via a pyrometer.

• The 6-axis industrial robot (Kuka KR 30-3) with two integrated additional axes via a rotary-tilt table enables flexible, three-dimensional machining.

• Various automation options can be flexibly integrated via the robot control system.

• The offline programming and simulation of the robot is done via the software   RoboDK  .

For further cutting tasks in the field of metallic materials, a laser cutting machine with a fiber laser (Senfeng 1313G) is available:

• With a nominal optical power of 1500 watts and good beam quality, even thicker sheets can be cut.

• The laser properties also allow highly reflective metals (such as brass or copper) to be processed.

• The system can also be used to cut and engrave fine contours.

The laboratory equipment is complemented by another laser system for surface processing:

• The solid-state laser (IPG Laser GmbH model: YLR-200) achieves a nominal power of 200 watts.

• The high intensity of the small spot enables rapid surface processing. The laser beam is moved across the workpiece by a scanner unit.

• With laser marking, contrasts or engravings can be created by applying heat to the surface.

• The high positioning accuracy enables the display of the finest images.

Exemplary work steps of the consulting service:

• Analysis of the task

• Test series with qualitative analysis (microscopy, material testing)

• Assessment, final recommendation and documentation
