SLT series

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.



Metallic pipes, cable shielding, stamping operations
