Laser hardening and welding

• No deformation of the part geometry compared to induction treatment. It is possible to detect small deformations on small workpieces. (in the order 1/10 mm)
• No need to rework the workpiece. Unlike the induction process, laser hardening is performed on the FINISHED workpiece.
• Greater depth and hardness process consistency.
• No need to cool the workpiece, thanks to an AUTO-OFF process performed by the material surrounding the zone being treated. The use of a coolant is INDISPENSABLE in the induction process.
• It is possible to change tje spot diameter during processing.

During the hardening process, the outside edges of the beam have a tempering effect on the previous pass. In this transition zone between the two passes, there may be a loss of hardness, which can vary from 4–6 rockwell points in the order of 1–1.5 mm for cast iron, and 2–3 rockwell points in the order of 0.5–1.0 mm for steel.

Minimum spot aperture: 6×6 mm

Maximum spot aperture: 45×5 mm

NB: The head is interchangeable. A variant with a minimum aperture of 4×4 mm and a maximum aperture of 40×5 mm is available.

A module with thermal video camera makes it possible to view the laser spot in real time, together with information about the processing temperature.
The camera shows the temperature as a multi-coloured image.
This module allows the machine to autonomously monitor and regulate the temperature needed for the treatment.
