Keywords Friction stir welds, Welding defects, Tensile properties, Fatigue resistance 1. Introduction Friction stir welding (FSW) of so-called non-weldable Al-Cu alloys has been developed to substitute riveting in lightweight structures [1]. It allows avoiding hot cracking and limiting component distortion.FATIGUE BEHAVIOR OF SHIPBUILDING ALUMINIUM Friction stir welding, Gas metal arc welding, Tensile efficiency, Fatigue behavior INTRODUCTION Friction Stir Welding (FSW) was a remarkable development in the recent history of the welding technology resulting in metallurgical, environmental and energy benefits, allowing high quality of bothFSW process variants and mechanical properties - TWIFig.1. Lap weld joint configuration a) Advancing side near the top sheet edge (ANE) b) Retreating side near the top sheet edge (RNE) In order to provide a comparative reference for the fatigue performance of the Skew-stir TM lap welds, an 'artificial lap' of similar geometry was made from parent material, see Figure 2.These 'artificial lap' test pieces were made from solid material.
