Preparation lines
An overview of a deeply customized solution
The preparation lines can be designed for the most different process depending on the coil’s intended use after preparation. The coil-to-coil laser welding unit grants a reliable weld seam and an aesthetically pleasing joint. Typical application may be:
- Off line preparation of GO electrical steel coils with Laser Scribing technology (LSL | Laser Scribing Line)
- Joining of different coils for the preparation of a large coil (CJL | Coil Joining Line)
- Welding of head and tail to coils intended to be finished in a reverse mill (C2T | Coil to Tail Line)
The preparation lines are deeply customized to the customer’s needs, offering significant economic benefits and a short return on investment..
Coil to Tail
C2T | Coil to Tail preparation line
The Coil to Tail preparation line has been specifically designed and optimized for the preparation of the Coils to be processed in a Reverse Mill, significantly reducing the production costs (scrap costs) and with an important optimization of the process efficiency and performances.
The unit is optimized to the joining of material with different characteristics. The use of a full Laser Welding unit (C2C) integrated in the line, grant the user a very reliable process and a strong and rollable weld.
The line is normally designed to ad a section of low cost material to an added value coil. At the end of the Reverse Mill process, such low cost material is wasted instead of the added value one.
It is an easy calculation to verify the short return of investment of such installation.

Laser Scribing
LSL | Laser Scribing Line
The transformers industry is using more and more high quality “laserized” Grain Oriented Electrical Steel for its significant benefits on the core loss reduction.
The LSL can be applied to any quality of GOES, preserving the coating and increasing the final performance of the transformer. The line, being totally independent by the cold rolling mill or by the thermo-flattening process, can be used and applied as an offline finishing process at the steel producer side as well as a first step of a slitting plant dedicated to transformer steel.
The unit is normally designed including an entry and exit sections equipped with uncoiler and recolier, and a CCW Coil to coil welding unit to guarantee the continuity of the process.
The processing unit in this case will be the LSM Laser Scribing unit
