The purpose of this work is to validate the thermal welding cycle obtained experimentally with the metal inert gas (MIG) welding process on a 6063-T5 aluminium tubular profile using the finite element method. The assembly formed by the tubular profile and the weld bead obtained experimentally is represented in an accurate way, taking care of both the geometry and the contour of the weld bead. The precision achieved in the numerical-experimental validation carried out by means of the finite element method is due to the care that has been taken in drawing the welded piece together with the weld bead made experimentally. In the validation carried out, the experimental and numerical cooling curves and the critical cooling time between 400 and 300 ºC (t 4/3) in both curves are compared.

The aim of this work is to carry out the design of experiments that determine the influence of the welding parameters using Taguchi’s method on the grain size, HAZ, and the degree of dilution in 6063-T5 alloy. The welding process used is GMAW and the welding parameters are power, welding speed and bevel spacing. The study of the influence of the welding parameters on the measurements made in the welding (which are the size of 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 most influential in minimising the three measurements will be determined.

“…Taguchi method is one kind of optimization schemes with extraordinary efficiency and strong reliability for different manufacturing processes. Meseguer-Valdenebro et al [2] utilized the Taguchi experiments with three variables (power of the heat source, welding speed, and separation of the edges) and selected the height of the welding bead, welding bead width, the penetration depth, the perimeter of the weld bead, and the area of the welding bead as the welding bead geometric features. The effects of the three welding parameters on the welding quality were also investigated.…”

The profile of the welding bead changes with the welding process parameters during the gas metal arc welding (GMAW) process, the reinforcement disappears and the penetration becomes sunken when the excessive welding heat input is applied. However, little research work is specially planned to cope with the studying of welding bead at these stages. A systematic studying of the relationships among the welding process variables and welding bead geometric features and optimization of the welding quality is presented. The influences of the welding technological parameters (voltage, welding speed, and wire feed speed) on the welding geometry were revealed and the models correlating them were established. The features of the weld bead geometry were composed of top reinforcement width, top reinforcement height, penetration depth, bottom reinforcement width, and bottom reinforcement height. By the desirability function approach, the recommendation of suitable welding parameters to meet the contradicting demands of multiple bead geometric features is fulfilled. The microstructure in different welding regions and mechanical performances of the welding joints produced by the verification test were also studied.
