The primary field of application for thin section stainless steels has traditionally been to provide a corrosion resistant surface. More recent applications of these materials have also concentrated on structural applications and there is an increasing demand for data concerning the properties of welds. Laser welding is ideally suited to the joining of thin section stainless steel sheets and this paper presents the results of an investigation into the fatigue properties of such welds. The work investigates the influence of sheet thickness, weld width, porosity and inter-sheet gaps on the fatigue life of the welds. Fatigue tests were carried out on thin section stainless steel lap welds produced by Nd:YAG-laser. Analysis of the fatigue tests results and the fracture surfaces identified sheet thickness and inter sheet gaps as having considerable effect on fatigue life. Weld width has a more moderate influence on fatigue life and weld porosity has a negligible effect at low concentrations.
