Researchers at Germany’s Fraunhofer Institute for Laser Technology have developed a method to laser-weld transparent plastic components together, a task previously thought impossible
The degree of work hardening depends on the material, but it’s rarely a problem in most steel alloys. As a result, the formed bushing is remarkably strong and can be used for bearing sleeves or, when threaded in a separate process, provides high torque capacity and pull-out strength.
