“…The TIG/MIG-MAG hybrid welding process has been used when welding dissimilar materials according to studies by Ding et al [18] and Zhang et al [19]. A microstructural analysis of the welding of ferritic stainless steels with magnesium alloys was performed by Ding et al [18], in which they show that the hybrid welding process was efficient at producing joints with dissimilar materials.…”

“…A microstructural analysis of the welding of ferritic stainless steels with magnesium alloys was performed by Ding et al [18], in which they show that the hybrid welding process was efficient at producing joints with dissimilar materials. Zhang et al [19] welded-brazed stainless steels with aluminum by using a different configuration of the hybrid TIG/MIG process, i.e., the MIG torch was positioned on the top of the workpiece and the TIG torch on the bottom of the workpiece (MIG-TIG double-sided).…”

Abstract:The main aim of this work was to evaluate the influence and optimize the factors of the TIG-MIG/MAG hybrid welding process on the geometry of the weld bead. An experimental design using the Taguchi methodology (robust design method) was used to conduct the experiments. The experiments were carried out according to an orthogonal matrix with 27 experiments, with three replicates each, totaling 81 test specimens. The factors (MIG/MAG shielding gas type, MIG/MAG voltage, MIG/MAG wire feed, gas flow rate of TIG, electric current intensity of TIG and welding speed) were varied with three levels each. Penetration, heat-affected zone (HAZ), bead width and bead height were the response variables analyzed. The results showed that the penetration was significantly influenced by the MIG/MAG wire feed, MIG/MAG shielding gas type, MIG/MAG voltage and welding speed. The HAZ has been influenced by MIG/MAG voltage, MIG/MAG shielding gas type, welding speed and electric current intensity of TIG. All factors had effects on the width, except the MIG/MAG wire feed. The bead height was significantly influenced by the MIG/MAG wire feed and by the electric current intensity of TIG. Optimizing the process was performed, so that for each output variable, the values of the factors that should be used were indicated, and the optimization was confirmed by welding test specimens.

“…However, forming and welding of low density steels to other car body parts made of different alloy materials especially with steel parts is challenging due to the different physical, mechanical and metallurgical properties of dissimilar metals [6]. Arc welding processes which operates at very high heat input in comparison to EBW, favours the formation of different brittle Fe-Al intermetallics at the weld interface which deteriorates mechanical properties of weld dissimilar joints [7].…”

Electron beam welding (EBW) technique was used to perform dissimilar joining of plain carbon steel to Fe-7%Al alloy under three different weld conditions such as with beam oscillation, without beam oscillation and at higher welding speed. The effect of weld parameters on the microstructure and mechanical properties of dissimilar joints was studied using optical microscopy, SEM, EBSD, hardness, tensile and erichsen cup tests.

“…An appropriated selection of welding parameters is a fundamental aspect when a good quality of the weld bead is aimed at. The studies found in the literature on TIG-MIG/MAG involve various parameters and variables aiming at advances in areas such as welding speed [5,8], improvement in appearance and geometry of the weld beads [4,6,9], heat distribution in the joint, and so on [10,11]. It is noteworthy that all studies use the same configuration seen in Fig.…”

The associations of tungsten inert gas (TIG) and metal inert gas/metal active gas (MIG/MAG) welding process intends to take advantage of the higher productivity of the MIG/MAG process with the greater heat control imposed by the TIG process. In this context, the present study aims to evaluate the effects of the TIG-MIG/MAG process with both electrodes in direct (negative) polarity in weld bead geometry. A pioneering research on TIG-MIG/MAG process was carried out for the purpose of writing this article. Therefore, weld beads were made by the conventional MIG/MAG process and by the TIG-MIG/MAG process. Two input parameters, the MIG/MAG polarity and the TIG current, were evaluated. The output responses such as bead width, reinforcement, penetration, melted area, and convexity angles were evaluated. Macrographs were performed to measure the geometrical parameters of the weld bead. The results of these measurements were evaluated by a variance analysis. The results show that the polarity variation has an influence to modify the weld bead geometry in a TIG-MIG/MAG welding process. It was also noticed that the insertion of TIG current caused the tendency to greater wettability, penetration, melted area, width, and smaller reinforcements of weld beads.
