Laser welding plays an important role not only in sheet metal processing, but also in the research work carried out at the LZH. Highlights at the fair EuroBLECH include laser welding of 23 mm thick metal sheets for ship building or pipeline construction, or how lasers can be used for welding a three meter long ship rudder made of steel-aluminum sandwich plates, cutting the weight of the rudder in half.
At the EuroBLECH fair, the LZH will be showing how laser welding can be used for weight reduction in shipbuilding (Hall 11, Stand H 08). The ship rudder in the photo is made of laser welded steel-aluminum sandwich plates (see cross-section).
Even if laser cutting has been well established for several years, there are always new challenges. The LZH will be showing that lasers can be used to economically cu many different materials (e.g. alloys and non-ferrous metals) and different material thicknesses.
Laser surface treatment is interesting for rapid prototyping, for generating small structures (laser sintering) with a resolution of only 30 µm. The LZH will also be showing how laser deposition welding and repair welding can help reduce costs, for example for repairing so-called blisks (a turbine or engine component consisting of a single element combining the rotor disk and the blades).

The Fraunhofer Institute for Organic Electronics, Electron Beam and Plasma Technology FEP has been developing various applications for OLED microdisplays based on organic semiconductors. By integrating the capabilities of an image sensor directly into the microdisplay, eye movements can be recorded by the smart glasses and utilized for guidance and control functions, as one example. The new design will be debuted at Augmented World Expo Europe (AWE) in Berlin at Booth B25, October 18th – 19th.

With the help of artificial intelligence, chemists from the University of Basel in Switzerland have computed the characteristics of about two million crystals made up of four chemical elements. The researchers were able to identify 90 previously unknown thermodynamically stable crystals that can be regarded as new materials. They report on their findings in the scientific journal Physical Review Letters.

For the first time, Fraunhofer IKTS shows additively manufactured hardmetal tools at WorldPM 2016 in Hamburg. Mechanical, chemical as well as a high heat resistance and extreme hardness are required from tools that are used in mechanical and automotive engineering or in plastics and building materials industry. Researchers at the Fraunhofer Institute for Ceramic Technologies and Systems IKTS in Dresden managed the production of complex hardmetal tools via 3D printing in a quality that are in no way inferior to conventionally produced high-performance tools.
Fraunhofer IKTS counts decades of proven expertise in the development of hardmetals. To date, reliable cutting, drilling, pressing and stamping tools made of...
At AKL’16, the International Laser Technology Congress held in May this year, interest in the topic of process control was greater than expected. Appropriately, the event was also used to launch the Industry Working Group for Process Control in Laser Material Processing. The group provides a forum for representatives from industry and research to initiate pre-competitive projects and discuss issues such as standards, potential cost savings and feasibility.
In the age of industry 4.0, laser technology is firmly established within manufacturing. A wide variety of laser techniques – from USP ablation and additive...
Every three years, the plastics industry gathers at K, the international trade fair for plastics and rubber in Düsseldorf. The Fraunhofer Institute for Laser Technology ILT will also be attending again and presenting many innovative technologies, such as for joining plastics and metals using ultrashort pulse lasers. From October 19 to 26, you can find the Fraunhofer ILT at the joint Fraunhofer booth SC01 in Hall 7.
K is the world’s largest trade fair for the plastics and rubber industry. As in previous years, the organizers are expecting 3,000 exhibitors and more than...
