From Micro-Structures to Shipbuilding: Laser Technology at the Hannover Messe 2013

18.03.2013
Laser technology – from micro-structures to shipbuilding – is an integral part of the Hannover Messe. Accordingly, the Laser Zentrum Hannover e.V. (LZH) has been an exhibitor at the world’s largest industrial fair for almost 20 years.
This year, the LZH will be exhibiting innovative developments and applications in the fields of “Laser-based Manufacturing Technologies” and “Laser Precision Processing”.

Laser Precision Processing
An interesting example of laser precision processing is strain gauge sensors, which can provide exact measurements of strain and stresses in machines, bearings or motors. Since sensors are subject to rough environmental conditions such as high temperature change and mechanical and chemical stresses, they must be extremely robust. Conventional sensors are manufactured on foils or thin films, which are then affixed to the machines using adhesives, and unfortunately, the adhesives are sensitive to the rough conditions in machines or motors. Laser technology can overcome this limitation by structuring strain gauges directly on the surface of a component. These sensors are extremely robust and can even be placed on complex components with cylindrical, spherical or free-form shapes.

Further fair exhibits in the field of laser precision processing are laser structured surfaces which are highly water repellent (superhydrophobic), or solar cells which provide higher efficiency and energy output, due to laser processing.

Laser-based Manufacturing Technologies
Laser-based manufacturing technologies play an important role not only in production, but also in the research work being done at the LZH. Research topics range from using selective laser melting to generate tiny metal components up to welding 23 mm thick steel sheets, as used in shipbuilding or pipeline construction.

A good example illustrating the diversity of the tool „laser“ can be seen in laser processing of the light weight material CFRP (carbon fiber reinforced plastics), which is being used more and more in modern aviation applications. CFRP can be cut, drilled, structured and ablated using the laser, and it is even possible to weld plastics to CFRP components.
Another field for “laser lightweight construction” can be found in shipbuilding. The weight of large sized units can be cut in half by using laser welded sandwich material, steel sheets with an aluminum foam core. These lightweight steel-aluminum structures are difficult to weld, as cracks in the welding seams must be avoided, and a zero gap is required. LZH researchers, together with their project partners, could successfully laser weld ship structures made of Fe/Al sandwich materials for Blohm + Voss Naval GmbH in Emden, Germany. The results can be seen at the Hannover Messe.
