When laser-hardening â€“ also referred to as marginalized layer hardening â€“ the laser beam with its adjustable focal spot size is guided over the welded surfaces by a robot. The energy of the laser is applied directly to the workpiece surface. This marginalized layer is then heated in a very short period of time and locally limited to the required hardening temperature. The integrated temperature measurement in the beam geometry ensures that the heat input is uniform. The laser beam's interaction time with the surface determines the hardness penetration depth.
The advantages of laser hardening can be summarized as follows:
