Description
An investigation is presented into the development of a flexible 3D friction stir welding (FSW) process capacity incorporating a rail mounted industrial robot to facilitate high production rate repair of aluminium cathodes for electro refining operations. The industrial need related to extension of the service life of AA 1070-H14 and AA 1370-H14 plates subjected to corrosion in zinc electrowinning procedures. Process development was performed on an MTS I-STIR FSW machine using rectangular coupons in a butt joint configuration. FSW experiments were conducted for similar AA 1370-AA 1370 and dissimilar AA 1070-AA 1370 combinations in order to study the influence of weld pitch on pin clearance window width. The effect of corrosion attack after electrolytic cell service was examined. Other issues discussed include enabling technologies for process robotisation and path accuracy management, robotic FSW real time process control and automated clamping systems.
