Why Extraction and Filtration Technology is so important? The technologies of connection, separation, marking, drilling, sintering and milling, the utilisation of fluxes, 3D-printing processes, rapid prototyping by means of laser, soldering and gluing – all these processes generate harmful substances that might have extreme health impacts. Manufacturing processes have gained in complexity, and resulting pollutants have become smaller and particularly more exotic. Capturing and Filtering of airborne Substances is anything but simple.

Diode Lasers for Laser Cladding: status quo – quo vadis In the last couple of years new applications for lasers emerge from technological improvements in laser sources. They are replacing many traditional methods of industrial manufacturing, in particular welding, brazing and heat treatment. Another example for new applications enabled by the technological progress is laser cladding.
