Suitable for applictions requiring high productivity and high quality welding with minimum cold working of the strip.
No roll changes - Faster change over times - Very stable forming- Small fin pass reductions - Large V-convergence angles - Suppression of Roll Marks.- Improved elongation and less work hardening - Space reduction - Improved control of strip edges and reduced welding temperature variation.
