Austria: Bending and Laser Welding in One Production Step
Austrian collector manufacturer Tisun GmbH started operating a new type of absorber production machine at the beginning of November 2011. Developed and delivered by Austrian machine supplier DTEC GmbH, the special feature of the machine is its ability to bend and laser-weld parts in a single production step. “We have patented the three-dimensional head which bends, forms and welds the piping to the absorber plate,” explains DTEC’s Managing Director, Michael Dietl. The photo shows the multi-functional laser head with its tools installed in the factory.
