Abstract
The invention relates to a process for hardening the boundary layers of long workpieces using high-energy radiation, in particular laser radiation, by which the surface of the long objects are hardened using consecutive processing tracks of radiation. In order to harden with as little offset as possible, the process is designed so that after each processing track, at least one of the actual values of the torsion offset distributed across the long objects is determined, the sign of this torsion value is supplied to a computer, and the following processing track is automatically selected in the sense of a sign opposite to that of the torsion offset.
