Metal Coil Processing - Laser Cross Welding
Application Demand
In high-volume metal processing, coils must be joined end-to-end to maintain continuous
rolling, stamping or forming operations. The joints must be strong, defect-free and smooth to
prevent disruptions in downstream processes. This is especially critical for electrical steels
and grain-oriented electrical steels, where coil thicknesses range from 30 µm to 300 µm.
Precise welding angles and uniform fusion are required to minimize defects, reduce scrap
and maintain material performance.
What Laser Enables
Laser cross welding provides high-strength, consistent and defect-free cutting and joining of
metal coils together. The non-contact process ensures smooth transitions, precise angle
cutting and welding with minimal heat-affected zones, even on ultra-thin materials. It
improves production efficiency, reduces material scrap and supports high-speed, automated
coil processing while maintaining metallurgical integrity and electrical performance of the
steel.
