Abstract

Friction stir welding (FSW) is a new welding technique which has been applied to lightweight materials such as polymers. In this work, the feasibility of FSW on poly methyl methacrylate (PMMA) was investigated. For this purpose, an appropriate friction stir welding tool is used to make butt joint welded specimens. Experimental tests were carried out according to an L16 Taguchi design of experiments in which tool rotational speed, tool transverse speed, and tool penetration depth were applied as FSW parameters. In addition, the ductile behavior and weld appearance of welded samples have been studied. In order to determine the effects of FSW parameters on the weld strength, the signal-to-noise (S/N) ratio and analysis of variance (ANOVA) were utilized. According to the ANOVA results, the tool transverse speed has a significant effect on the weld strength. Also, the contribution of each FSW main factor and their interaction have been determined. This study demonstrates that friction stir welding of PMMA is feasible and the range of FSW parameters that provide acceptable welds are designated.
