IN-LINE METHOD AND IN-LINE PRODUCTION PLANT

摘要

The invention relates to an in-line method for producing workpieces or assemblies (2), in which method the workpieces or assemblies (2) pass through a number of successive workstations (4) by means of a conveyor device (3). Said method is characterised by a hardening step that is carried out in one of the workstations (4), during which step at least one region of the workpiece or assembly (2) is hardened by the application of at least one laser hardening trace (6) by means of a laser device (5), in particular, a laser with programmable focusing optics (PFO) or a linear laser. The invention also relates to a corresponding in-line production plant.
