Hybrid Solution Moves Boundaries of Copper Welding

For copper joining, blue diode lasers have made it possible to control heat conduction welding for the very first time. The technology, however, has reached its current limits with copper deep welding, where infrared lasers have also not achieved satisfactory results. A hybrid concept by Laserline that connects blue and infrared diode lasers has now opened up new manufacturing options. The approach does not only prove itself at the joining of sheets, but also at the static welding of hairpins – and in so doing moves the boundaries of copper welding altogether.
