Trumpf Group celebrates installation of 20,000th TruFlow C02 laser


The Trumpf Group has installed its 20,000th TruFlow laser, a 7 kW high-powered CO2 laser that has been integrated in a TruLaser Cell 1100 at the Fischer Group in Germany, where it will be continuously welding tubes and profiles.

One of the most significant features of TruFlow lasers, says Trumpf, is their wear-free, zero-maintenance system of gas circulation that uses magnetically suspended turbo blowers combined with the high frequency excitation of the laser gas.

This, the company stresses, minimises maintenance and operating costs, while maximising availability. The axial flow TruFlow lasers also exhibit "superb thermal and mechanical stability". Drawing on decades of development, this laser technology offers customers' "top-quality, repeatable machining".

Despite a degree of pessimism in the laser industry, Trumpf says it continues to believe in the future of CO2 lasers, as Dr Ing Christian Schmitz, who heads up laser development and production at Trumpf, explains: "The idea that CO2 lasers are somehow on the way out is a simple misconception.

"The wavelength of CO2 lasers continues to offer major benefits for certain applications. It is still the best option for customers who are looking to process the full spectrum of sheet thicknesses, and remains the number one choice for welding thick plates."

Trumpf supplies TruFlow lasers with output powers ranging from 700 to 20,000 Watts. Integration with a higher-level control system is said to be easy, so that it can be used in even the most challenging environments, the company says.
