Other Applications in Automotive Industry

The application field of lasers in the automotive industry is going beyond cutting-, welding- and marking applications. Lasers are also playing an important role when it comes to ablation, surface activation or brazing tasks. The q-switched high-performance lasers remove metallic coatings entirely, fast and economically for an optimal welding preparation. Thereby, the removing geometry on the work piece can be freely defined. Laser brazed connections do have the advantage that they create an even, clean surface with an oscillated transition between the work pieces.

Laser Ablation of Metallic Coatings of Tailored Blanks

Laser Ablation of Metallic Coatings of Tailored Blanks

Aiming at further improving the crash security of automobiles and at the same time cutting down on carriage weight in favor of mileage, the automotive industry uses more and more Tailored Blanks of high strength manganese-boric steel. To avoid a mixing of parent material with the applied coating of aluminum-silicon that is supposed to protect from scaling and corrosion, the coating has to be removed in the area of the weld.


For this application we recommend: DQ SeriesHighLight FL1000P

Laser Brazing of Automobile Hatches and Roofs

Laser Brazing of Automobile Hatches and Roofs

The automotive industry applies these material-locking joints in the production of hatches and automobile roofs as before the painting of the carriage no post processing of the brazed joint is necessary. To achieve stability, which is comparable to a weld joint automotive manufacturers focus on brazing. When applying brazing with so-called seamless joints, paintable and waterproof joints evolve without finishing.

For this application we recommend the diode laser: HighLight DL6000HP
