Abstract
Laser welding has an increasing role in the automotive industry,
namely on the sub-assemblies manufacturing. Several sheet-shape
parts are laser welded, on a dissimilar combination of thicknesses
and materials, and are afterwards formed (stamped) being
transformed in a vehicle body component. In this paper low carbon
CO2 laser welding on the thicknesses of 1.25 and 0.75 mm,
formability investigation is described. There will be a
description of how the laser welded blanks behave in different
forming tests, and the influence of misalignment and undercut on
the formibility. The quality is evaluated by measuring the limit
strain and limit effective strain for the laser welded sheets and
the base material, which will be presented in a forming limit
diagram.
