SLT 100M0°​

Laser cross welding

SLT series laser cross welders for perfect, precise, economic and efficient welding of a wide variety of tape materials, thicknesses and coil and steel sheet widths.

The SLT series cross welders are especially designed to be used in all kinds of situations as a stand-alone machine or for in-line processes. SLT series welds thin and thick alloys as well as coated and uncoated metal tapes, coils and large sheets in a fully automated cutting, positioning and butt welding process. Featuring consistency, replication and high quality of the welds.


Butt welding / joining of wide steel coils, Combining wide steel sheets, Wide industrial alloy production lines, Service centers for wide coil slitting operations, Steel sheet service centers

Features and benefits

•       Minimal foot print – narrow – wide machine       
•       Precise mechanical guiding and automatic aligning allow welding
        of tapes down to 0.05 mm thickness
•       Welding of alloy coils and sheets up to 1400 mm wide
•       Laser technology allows welding of copolymer coated tapes
        without pre-cleaning
•       Widest possible choice of weld-able materials
•       Menu- guided system for ease of use
•       Recipe controlled for assured repeatability
•       Robust construction for 24/7 operations
•       Easy to operate – no skilled labor
•       Repeatable high quality seams
•       No tape pre-cleaning or further machining required
•       Scrap avoidance due to reliable welding and full usage
        of all rest coils and steel sheets
•       Continuous production for any application, such as downstream
        slitting and coiling processes
•       Available on rails with motorization assist – extraction from
        production line
•       Available with weld ramps and weld annealing functions
