Process Engineering

This special field revolves around processes for modifying material properties (milling, cooling), composition (filtration, distillation) and type (oxidation, hydration).

Valuable information is available on a broad range of technologies including material separation, laser processes, measuring techniques and robot engineering in addition to testing methods and coating and materials analysis processes.

Laser Technique Shortens Welding Process for Heat-Treatable Steels

Heat-treatable steels are often used for highly stressed construction elements, since they show a high tensile and endurance strength resulting from the heat…

Higher Efficiency for Building Ships, Pipelines and Towers through Laser-GMA-Hybrid-Welding Process

In collaboration with seven partners, the Laser Zentrum Hannover e.V. (LZH) is developing a hybrid welding process which combines the advantages of laser and…

Laser Makes Conventional Welding Faster

In conventional GMAW, the electric arc naturally follows the path of least resistance between the electrode and the base material. The arc is difficult to…

Plastics laser welding with TransTWIST for invisible weld seams

At this year’s plastics trade show in Düsseldorf (October 27 to November 3, 2010) the Fraunhofer ILT is presenting the TransTWIST laser-based plastics welding…

Siemens develops leak location and monitoring system to reduce losses in drinking water supplies

Precise knowledge of water losses is essential for operating and planning the maintenance of drinking water networks efficiently. The condition of the pipes…

Environmentally compatible disinfection of drinking water

Five Siemens ultraviolet (UV) disinfection plants came into operation in May in the Echthausen Water Works belonging to Wasserwerke Westfalen GmbH, Germany.They have considerably reduced the amount of chemicals used by the drinking water supplier. This process also eliminates microorganisms which cannot always be adequately controlled by other disinfection processes. These new UV plants are part of Wasserwerke Westfalen's extensive investment project to further improve the quality of its drinking water….
