OPTIMIZATION OF THE FSW PROCESS FOR ALUMINUM ALLOYS AA5083 BY THE GREY-BASED TAGUCHI METHOD

摘要

Friction Stir Welding (FSW), invented by W.M. Thomas et al. [1], can produce superior mechanical properties in the weld zone. The purpose of this paper is to find the optimum operating conditions of FSW process for two plates of aluminum alloy AA5083 welded in butt joint. In the FSW procedure, there were four major controllable four-level factors, i.e., the tool rotation speed, transverse speed (feed rate), tool tilt angle with respect to the workpiece surface and pin tool length, as shown in Table 1.
