“FLUX-LMDR” intends to increase energy efficiency of transformers

The project “Technology for greater energy efficiency in distribution transformers” (FLUX-LMDR) was kicked off on 30  November 2017. Under the auspices of the Fraunhofer-Institut für Werkstoff- und Strahltechnik IWS Dresden, an alliance of five partners from science and industry will conduct research in laser processing of transformer sheets over the next three years. The application was approved by the Federal Ministry for Economy and Energy at the end of October. The Fraunhofer IWS will lead the technological development as well as take part in systems engineering.

 

futureAM – Next Generation Additive Manufacturing

On November 14th, 2017, the Fraunhofer focus project, futureAM, was launched in Aachen under the auspices of the Fraunhofer Institute for Laser Technology ILT. Six project partners – the Fraunhofer Institutes ILT, IWS, IWU, IGD and IFAM as well as the LZN Laser Zentrum Nord – have set themselves a clear goal: Over the next three years, they will work closely together to secure the prerequisites for significant technological leaps in additive manufacturing with metallic materials (metal AM).

 

Super-efficient – High-performance laser coated hydraulic cylinder rods

A higher laser beam cladding performance benefits Bosch Rexroth at the Dutch location Boxtel. The Fraunhofer-Institut für Werkstoff- und Strahltechnik IWS Dresden mutually optimized an industrial manufacturing process with the producer of drive and control engineering.

 

"MuReA" provides quick and large-scale laser applications

The Fraunhofer-Institut für Werkstoff- und Strahltechnik IWS developed the novel remote system concept (MuReA) for quick, flexible and efficient laser processing tasks. IWS scientists combined laser remote systems, spindle drives and high performance beam sources with each other. As a result, this novel laser system enables large-scale, flexible and quick processing tasks for materials such as aluminum, stainless steel as well as fiber reinforced polymers.

Due to digitalized product development and cross-linked manufacturing cycles development periods have been radically shortened. Rapid product change requires from manufacturers and suppliers a high rate of flexibility, so that customized and cost-optimized solutions can be offered. For the development of new laser welding technologies individualized processes tailored for specific materials and products need to be combined with innovative hardware concepts.

Joining technologies for electromobility

Within the framework of the joint project »BatCon«, funded by the Federal Ministry for Economic Affairs and Energy, Fraunhofer IWS scientists have developed novel property- and cost-optimized joining techniques for the fabrication of aluminum-copper cell joints over the past three years.
 

TAILORED JOINING – Joining technology experts focus their know-how in Dresden

Joining is the key challenge in production processes and often a significant cost factor. The knowledge and the selection of the appropriate procedure is therefore of the utmost importance. Within the framework of the 9th international laser symposium and the joining symposium “Tailored Joining” renowned experts will meet for an international exchange of experiences in Dresden on February, 22 - 24, 2016.

Diode laser and wire – a strong team for laser build-up welding and additive manufacturing

At this year’s LASER World of PHOTONICS in Munich the Fraunhofer IWS Dresden and Laserline GmbH, Mülheim-Kärlich will, for the very first time, present the wire processing optics, which has been qualified for the application with a high power diode laser for three-dimensional build-up welding and additive manufacturing tasks.
 

Better welding with speedy laser mirrors

Silicon micromirrors can guide laser beams at extremely high speeds, allowing operators to dose heat input to workpieces with absolute precision. But to date they have not been robust enough to be used for laser cutting and welding. Now a Fraunhofer team has managed to develop fast, durable mirrors that are capable of performing challenging cutting and welding tasks.
 

New perspectives for laser beam welding of die-cast aluminum components

Scientists of the Fraunhofer IWS Dresden in cooperation with an industrial partner have developed a new technique for the welding of die-cast aluminum components and have managed to transfer it into series production. For the very first time, a weld joint, which is characterized by extremely low porosity and strongly reduced distortion, is generated with the help of brilliant laser radiation and high-frequency oscillation.
 

World record for laser surface patterning: 0.7 m²/min with micrometer resolution!

The Fraunhofer IWS Dresden, which develops modular laser systems for high-speed laser patterning, has now set a new world record in this field. For the first time, scientists succeeded in achieving an effective patterning speed of 0.7 m²/min while micropatterning a polymer surface.
 

Dr. Jens Standfuß takes over the management of the business unit “Joining“

With effect from January 1, 2015 Dr. Jens Standfuß heads the business unit “Joining”. He succeeds Prof. Dr. Berndt Brenner, who celebrated his 65th birthday in November 2014. Prof. Brenner will be contributing his expertise to support his colleagues in their scientific research in the future.
