Laser machine enables coil joining in continuous strip processing lines

摘要

The global steel market is under constant pressure. Cost-reduction initiatives such as energy conservation, minimizing personnel, and spare-parts reduction come along with the need to increase the availability of equipment. Staying competitive comes with the necessity to offer a broad product portfolio, which focuses on modern steel grades. Old flash butt welding machines or conventional laser welding machines are not able to weld modern steel grades in a reliable manner, as their high-alloying contents have an influence on the weldability of the materials. Furthermore, welding machines in existing lines need to be replaced as spare parts and in-house expertise availability dwindle.
