Abstract
Resistance spot welding is the prevailing technology used to join metal sheets. To guarantee weld strength and prevent structural failure, reliable quality control tests are indispensable. In an effort to automise the predominantly manually performed inspection, novel methods for automated weld spot inspection need fast simulation models with reasonable accuracy for optimisation. This work describes the process by means of a multiphysical FEM simulation of a spot weld measurement procedure. Various simulation approaches were used to obtain the best matching results with experimental data.
