The "FlexiFab" project: Breakthrough in friction stir welding through an automated robotic system


News

The aim of the “FlexiFab“ project was to develop a flexible Friction Stir Welding (FSW) system capable of automatically fabricating complex structures, in a variety of joint configurations, from a range of aluminium alloy grades and thicknesses used in the transport sector. Aluminium has several unique characteristics which need to be considered when fusion welding. Without care given its reactivity to air and high thermal conductivity/expansion, welds are prone to a wide variation of defects such as undercutting, excessive melt-through, incomplete fusion, incomplete joint penetration, porosity and cracking.
