By Philipp von Witzendorff, Lorenz Gehrmann, Martin Bielenin, Jean-Pierre Bergmann, Stefan Kaierle and Ludger Overmeyer Pulsed laser welding is applied for welding of thin aluminum sheets when the heat affected zone has to be minimized. The pulsed laser process enables a low and precise heat input because the heat dissipates away in between the laser pulses. […]

Laser Cleaning of Carbonaceous Deposits on Combustion Engine Components
By Yingchun Guan, Chih-Hsing Liu, Gnian Cher Lim, Hong Yu Zheng and Ming Hui Hong Carbonaceous deposits covering the surfaces of combustion engine components are known to cause abrasive wear, leading to increased oil consumption and reduce engine durability as well as performance. Remanufacturing is the process acting on end-of-life products to recover manufacturing standards and […]
Laser Applications in the Automotive Industry
By: Klaus Loeffler TRUMPF Laser und Systemtechnik GmbH, Ditzingen, Germany The automotive industry has been a target market for the laser soon after the invention of the laser in 1960. Mass production and flexibility have been the arguments for the laser. The first installations in 1973 all the way to late 1980 have been successful due […]
Picosecond Laser 4-Beam Interference Ablation of Metal Films for Microstructuring
By: B. Voisiat, M. Gedvilas, G. Raciukaitis Laboratory for Applied Research, Center for Physical Science and Technology, Lithuania Properties of the surface highly depend on its relief. The best example is a lotus leaf with the “self-cleaning”, hydrofobic feature. Micro- and nano-structuring with specific patterns and at localized places is useful to control wettability, lubrication and […]
