Abstract
A workpiece made of plate is subjected to a treatment which locally modifies its magnetic permeability. Subsequently, the magnetic permeability of the workpiece is examined locally resolved by a probe in order to find at least one surface region which is suitable for intended processing, and the processing is performed locally limited to the selected region.
Claims18
A method for processing a workpiece made of plate comprising:
- treating the workpiece to modify a magnetic permeability of a local region thereof;
- subsequently examining the magnetic permeability of the workpiece to find at least one surface region which is suitable for an intended processing;
- and
- processing the workpiece to perform the intended processing relative to the at least one surface region,
- wherein treating the workpiece comprises alloying an additive material into the local region of the workpiece.
