Abstract
This work presents a comparison between laser weld (LBW) and electric resistance spot weld (ERSW) processes used for assemblies of components in a body-in-white (BIW) at a world class automotive industry. It is carried out by evaluating the mechanical strength modeled both by experimental and numerical methods. An “Arcan” multiaxial test was designed and manufactured in order to enable 0°, 45° and 90° directional loadings. The welded specimens were uncoated low carbon steel sheets (Sy = 170 MPa) used currently at the automotive industry, with two different thicknesses: 0.80 and 1.20 mm. A numerical analysis was carried out using the finite element method (FEM) through LS-DYNA code.
