Abstract

The report presents the trial to correlation between roughness and vibration in friction stir welding of two aluminum plates. The transverse acceleration of the welded plates during welding was measured. The velocity and displacement in the transverse direction were determined by numerical integration. The welded joint was scanned and the profile in the joint area of the parts was obtained. The displacement results were compared with the roughness results. An analysis of the deviations in the two results was performed.

Keywords: Friction stir welding, vibration measurement, seam roughness, scanning
