Evaluation of progress and rotation parameters for welding process aluminum by FSW

Abstract

This article reports the results of stress tests on AA1050 aluminum plates butt welded by the process Friction Stir Welding (FSW), a vertical milling machine for that ROMI U-30 3Hp power and a welding tool used (PIN ) designed in SolidWorks and made in steel AISI 3115 carburized. The specimens were prepared butt under the AWS D1.2 / D1.2M: 2008 standard, with 39 weld beads made and tested. The rotational speeds were evaluated 710, 1000 and 1500 rpm, while the feed rates were 40, 60, 90 and 120 mm / min. The highest binding efficiency was obtained with the highest values of forward and revolution, corresponding to 72% of the strength of the base metal. From the results it can be concluded that with increasing feed rates and rotation resistance increases tension abutment in aluminum plates welded by FSW.
