Abstract
Abstract The aim of this work is to design experiments using Taguchi’s method that determine the influence of welding parameters on the grain size, heat-affected zone and degree of dilution of the 6063-T5 alloy. The welding process used is GMAW, and the welding parameters are the power, welding speed and bevel spacing. The study of the influence of these welding parameters on the measurements made during welding (which are the size of the heat-affected zone, the degree of dilution and the grain size) allows one to determine the quality of the joint. In addition, the welding parameter that most influences the minimisation of these three measurements will be determined.
