There is a clear trend in both the transport and the automobile industries towards light-weight construction using high-strength sheets made of stainless steel and aluminum. Especially SMEs (small and middle sized enterprises) are interested in fast manufacturing processes without quality losses, to maintain a high competitive position on the market. For this reason, the goal of the project CLAiM (Customised Laser-Aided Plasma Arc Welding of Light Alloys and Steels) is to shorten the processing time for established plasma welding processes, and at the same time to significantly increase welding seam quality.
The basic idea is to use a laser-stabilized welding process, such as a similar process with excellent results for light arc welding. Combining a laser with 400W output and a plasma welding source can bring about a 50% increase in the maximum welding speed. This would not only reduce the heat input into the metal sheet, but also significantly improve the weld seam quality. A further aim of the project is to achieve a 30% increase in the welding depth.
The project was introduced to about 50 participating enterprises at the first CLAiM workshop in Turkey this spring. At the workshop, the German firm Merkle presented the necessary welding system, the Laser Zentrum Hannover e.V. (LZH) explained the process idea, and the Spanish partner Tecnalia the welding process control concept. Also, the Turkish companies at the workshop were informed of the possibilities of participating in EU projects and in further funding initiatives for cooperating with German partners. Professor Arif Demir, vice-president of the university of Kocaeli, hosted the workshop.
An important goal of CLAiM is to strengthen the position of SMEs on the market by providing a significantly improved welding process for sheet metals, with low investment costs. “The high number of SMEs participating in the workshop was great for a kick-off meeting”, says Jörg Hermsdorf from the LZH. “By starting with close cooperation with small and middle sized enterprises, we can expect a quicker transfer of the project results to the target group.”
In the project CLAiM, two European research institutes and four industrial enterprises will be working together until September, 2012: Tecnalia Automotive and Taller de Modelos y Troqueles, S.L. (Spain), Form Engineering Ltd. (Turkey), Laser-Tech (Czech Republic) as well as Merkle Schweißanlagen-Technik and the Laser Zentrum Hannover (Germany). The research and development activities are financially supported by the 7th framework program of the EU. Project management is carried out by the REA-Research Executive Agency htpp://ec.europa.eu/research/rea [FP7/2007-2013] [FP7/2011-2013], proposal n° .Contact:

On the way to an intelligent laboratory, physicists from Innsbruck and Vienna present an artificial agent that autonomously designs quantum experiments. In initial experiments, the system has independently (re)discovered experimental techniques that are nowadays standard in modern quantum optical laboratories. This shows how machines could play a more creative role in research in the future.
We carry smartphones in our pockets, the streets are dotted with semi-autonomous cars, but in the research laboratory experiments are still being designed by...

For the first time, scientists have precisely measured the effective electrical charge of a single molecule in solution. This fundamental insight of an SNSF Professor could also pave the way for future medical diagnostics.
Electrical charge is one of the key properties that allows molecules to interact. Life itself depends on this phenomenon: many biological processes involve...
At the JEC World Composite Show in Paris in March 2018, the Fraunhofer Institute for Laser Technology ILT will be focusing on the latest trends and innovations in laser machining of composites. Among other things, researchers at the booth shared with the Aachen Center for Integrative Lightweight Production (AZL) will demonstrate how lasers can be used for joining, structuring, cutting and drilling composite materials.
No other industry has attracted as much public attention to composite materials as the automotive industry, which along with the aerospace industry is a driver...
Scientists at Tokyo Institute of Technology (Tokyo Tech) and Tohoku University have developed high-quality GFO epitaxial films and systematically investigated their ferroelectric and ferromagnetic properties. They also demonstrated the room-temperature magnetocapacitance effects of these GFO thin films.
Multiferroic materials show magnetically driven ferroelectricity. They are attracting increasing attention because of their fascinating properties such as...
