Abstract

Due to the distinctive characteristics of the existing welding technologies, it is important for a company to have methods that supports the selection of the best welding option for each application, to promote the efficient use of resources, as well as to optimize the production of the evaluated application. Thus, this work aims to propose a decision-making method for the selection of welding technology based on the AHP COPRAS tool. Field research was conducted in a metallurgical multinational company to identify which were the most relevant criteria related to the welding process. Through interviews with welding specialists, it was possible to identify and quantify four different criteria: Safety and Ergonomics, Quality, Productivity, and Cost. Based on these criteria, the AHP COPRAS tool was applied, and the results found that, for the case analyzed, the automated process was the best alternative when compared to the manual process.
