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. This removing becomes economically practical with the new q-switched high-performance lasers of the DQ series. The laser removing renders the complete elimination of any kind of metallic coating of Tailored Blanks possible while offering optimal economic marginal conditions.
The new 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.
For this application we recommend the: DQ Series
