Laser Scribing System

BAIDEL Group's laser scribing process and system have been developed with the aim to modify, opportunely, the state and size of the magnetic dominions in grain oriented electrical steel (GOES) sheets and coils through the use of laser sources, in order to increase the overall material efficiency reducing its core losses. 

This effect is obtained irradiating a specific portion of the surface of the GOES sheet with a laser beam whose energy density and whose interaction time are carefully determined and controlled in order to:

• ensure the reduction of the core losses due to hysteresis cycle, when the material is subject to the action of an oscillating magnetic field 

• reduce the core losses due to eddy current

• avoid any damage to the surface coating

FIELDS OF APPLICATION

BAIDEL Group's Laser Scribing System is designed for special application on Grain Oriented Electrical Steel. 

The Laser Scribing System can be integrated: 

• at the end of existing thermoflattering line (on-line system)

• in a stand alone system with dedicated decoiling and coiling unit (off-line system – Laser Scribing Complex)
