Description
Summary:Welding is a widely used manufacturing process that has a significant impact on the sustainability dimensions represented by environmental, economic and social aspects. In this work, a general and comprehensive framework for sustainability assessment of manufacturing processes is applied to select the most sustainable welding process among several alternatives for a certain application. The considered alternatives are friction stir welding (FSW), gas tungsten arc welding (GTAW), gas metal arc welding (GMAW), and shielded metal arc welding (SMAW). The four processes are used to weld two aluminum plates. Relevant sustainability indicators are selected from all sustainability dimensions. A dimension for physical performance of the welded parts is also considered. Entropy weight method is used for assigning weights to the indicators to avoid uncertainties of subjective weighting. Three multi-criteria decision making methods (MCDM) are used for normalization and aggregation of data. The reliability of the results is investigated by conducting sensitivity analysis. The results of the study show that FSW is the most sustainable welding process for this study.
