Mechanical properties of hybrid laser-MIG welding and spot welding on lap joint
2008 (English)Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
Abstract [en]

This thesis presents an investigation about hybrid laser welding and spot resistance welding in construction steels. Lap joint is used in all the experiments in order to compare different processes. FEM model of hybrid laser welding is also compared with result from mechanical tests. A study of how different set up affect to weld quality and mechanical properties is carry out. A comparison with spot welding is studied as well as between hybrid welding and a FEM model. Macro and micro examination, hardness tests, tensile tests were carried out in order to perform this study.
