Can lasers perform welds precisely and reliably in the midst of thundering machinery? The prototype of a new laser welder developed by an international team of researchers has now withstood the worst.

However, the liquid in the tank outside the tubing that absorbs the heat is chemically inert. Cost-effective materials can be employed here. Where tank and tubing meet, differing materials must be joined. “Traditional welding techniques hit their limits here, whereas the job can be handled with the laser,” says Herwig. The researchers are confident that laser welding can be implemented so effectively in production that European companies remain competitive internationally.

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.
The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".
Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
