Description
The StiRoLight Research project (carried out in conjunction with SAAB, ESAB and Volvo) to investigate the use of an industrial robot for friction stir welding of aluminium alloys in the automobile industry, is outlined and studies of path deviations and complexity introduced by preheating effects introduced. The project objectives are outlined with emphasis on changes, due to motion and configuration affecting the ability to weld a component in terms of force capacity, compliance and drift. An ESAB Rosio robotic system with an integrated welding head, equipped with a force sensor to compensate for error in position due to high forces acting on the system, was used in experiments. 3 mm aluminium sheets (AA2024-T3, AA5754, AA6063-T6 and AA7075) were linearly welded in butt configuration with a wide range of welding speeds and forces. Measurements were taken of path deviations and also of temperature to examine the preheating effect that occurs while welding on more complex paths.
