Today’s mobility and powertrain concepts are in a state of disruption, especially in the automotive industry. Solutions are needed that meet the general trends towards reduced CO2 and pollutant emissions, higher traffic density and increasing digitalization. The focus is on…
As an alternative to conventional laser welding, laser welding of plastics with wavelengths in the range of 2µm can be used. With this variant, two workpieces can be joined without additional absorbers. The main difference of the process lies in…
Laser transmission welding of plastics is dependent on a laser-transparent and laser-absorbing joining partner, which are connected in an overlap weld. Usually, the necessary optical properties are adjusted by additives. In the simplest case, carbon black is added to the…
In simultaneous welding, the entire weld seam is heated and melted at the same time (i.e. simultaneously) by one or more beam sources. The arrangement of the beam sources or the beam shaping by means of suitable optical elements must…
In so-called quasi-simultaneous welding, the weld seam is repeatedly scanned at high speed with a focused laser beam. The feed rates are usually above 300mm/s up to several meters per second. All areas of the weld seam are heated and…
