Coil-to-coil joining with laser welding in particular for 'Sophisticated Steel Grades'

摘要

With the development of new advanced high-strength steels, especially for the automotive industry, new challenges have become evident when coil joining such steels in continuous process lines with conventional butt-welding machines. Laser coil joining is becoming the preferred method for coil strip joining. This work discusses the advantages and benefits and why it is the method choice for new processing lines.
