AboutSLT 200​

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 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 alloy tapes as well as coated and uncoated ones in a fully automated cutting, positioning and butt welding process. Featuring consistency, replication and quality of the welds.

Features and benefits

•       Precise mechanical guiding and automatic aligning allow welding of tapes
        down to 0.05 mm thickness
•       Laser technology allows welding of copolymer coated tapes without
•       Widest possible choice of weld-able materials
•       Menu- guided system for ease of use
•       Recipe controlled for short cycle time and 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
•       Machine available on wheels and can be re-positioned manually or with a pallet jack lifter 
        (Special solutions on request)
•       Available with seam pressing unit – smooth welds
•       Available with weld ramps and weld annealing functions
