Enhancement of the Stringer Sheet Forming Process Chain by Means of Laser Fillet Welding

Lightweight construction continues to be of outstanding importance for many industrial sectors, and often relies on ribs or stringers to stiffen flat surfaces. Stringer sheet forming provides an efficient path to produce stiffened parts avoiding the disadvantages of milling or casting these structures. However, due to the deep penetration welding process, the first part of the process chain, stringer sheet parts are limited in terms of material choice and surface quality.
