Production method for motor vehicle floor module with central tunnel uses deep drawn profiled tunnel blank, cut into half sections, and connected along long edges by Laser welding

摘要

Two tunnel profile half sections (5,5') are deep drawn from plate material, the sections are joint with an overlap along their side edges extending in longitudinal direction, to form a tunnel top (6), and the free side edges (8) are connected to side plate panels (3,3') on either side of the central tunnel. Initially, a profiled tunnel blank is deep drawn from a panel, the profile is cut longitudinally into two halves, and the side edges are connected by welding, esp. Laser welding.
