Rofin-Sinar Technologies Inc. of Plymouth, Mich., is introducing its laser-welding technology for joining plastics parts, called StarWeld Diode.
The product family includes the HQ series of highly focused lasers and powerful, high-speed la-sers under the HP series. The power spectrum ranges up to 150 watts, depending on the application.
In StarWeld Diode equipment, two rotating mirrors move the diode laser beam across the workpiece.
The diode modules use a patented principle of “beam shaping,” which Rofin-Sinar claims guarantees a high-quality beam.
The lasers can do contour welding. That means the laser moves via an axis system or a robot over the counter of a part. That allows the welding of components of almost any size, the company said.
Another available method is called quasi-simultaneous welding, which means the laser is moved very quickly across the part several times. Because plastics have low thermal conductivity, the welding path heats up gradually and evenly, so that the entire area melts at nearly the same time.
