To fulfil a need of limitation automotive emissions the reduction of vehicle weight is widely recommended and achieved in many ways, both by the construction of individual elements of the vehicle, and by the selection of light materials including Al alloys. Connecting these elements with each other and with elements made of iron alloys can be realized, inter alia, by welding or stir welding. However, the quality of the welds obtained varies widely and depends on many design, operational and environmental factors. The present study focused on a review of various welding technics used to joint both similar and dissimilar Al alloys utilized in automotive industry, the effect of various process parameters on welds quality, and phenomena appeared in such welds..

“…The CMT process is highly similar to another layer deposition method -the cold arc pulse mode. However, the heat input during the two processes is substantially different due to the different mechanism of bead separation and integration in the molten phase of the component [6][7]. Since there is almost no information regarding the thermal fields generated during the cold arc pulse mode and their distribution within the volume of the specimen this work hopes to give some preliminary insight on that topic.…”

This work presents a preliminary experiment used to determine the possibility of developing a thermal model used to predict the thermal gradients formed during the process of wire and arc additive manufacturing (WAAM). For this purpose, an Al99.7 specimen was built using gas metal arc welding (GMAW) in the cold arc pulse mode. The temperature of both the substrate and each consecutive layer was measured using thermocouples and infrared thermometers and the experimental data was used for the calibration of the developed thermal model. The obtained results can be used for the further development of the thermal model.

“…As a result, regardless of the surface to be joined or the rate of joining, the arc's stability is perfect, allowing CMT welding to be used in any position and for any application [8]. CMT-WAAM is recognized as a smooth and emerging technology [9]. Because of its high efficiency, low heat input , and low cost, this is a potential method for the production of huge and intricate parts with feasible deposition rates [10,11].…”

A hybrid approach consisting of multi-objective and multivariate analyses for WAAM specimens

In this study, a combination of multivariate and multi-objective analyses, namely principal component analysis with fuzzy logic, has been proposed to identify the input parameters for ER4043, aluminum alloy in wire arc additive manufacturing. Taguchi L9 orthogonal array was designed with three-factor, three-level input parameters. Mechanical properties such as tensile strength and hardness were used as the output parameters. As the Taguchi optimization is not sufficient for multi-response optimization, observed data for each response were normalized and then principal component analysis was applied. Further, multi-response performance index (MRPI) was identified using fuzzy logic approach so that this hybrid approach could be successfully applied and MRPI could give a combination of input parameters at an optimal level.
