This paper presents a study of the influence of MIG welding process parameters on the weld bead geometry of 6063-T5 aluminium alloy. The welded profile is a longitudinally cut tubular profile that has been joined by a weld bead to make a butt joint. The influence of the electrical parameters employed, welding speed, power, and separation between edges is relevant to determine the influence of the electrical parameters of welding in each of the pieces that configure the weld. The analysed parts of the weld bead include bead height, root width, penetration, over-thickness (face), over-thickness (root), perimeter, and area of filler material. Studying the geometry of the bead weld is of great importance because the shape can condition other factors such as stress concentrators and fatigue behaviour.
