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..

To fulfill the need to limit automotive emissions, reducing 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 techniques used to join both similar and dissimilar Al alloys utilized in the automotive industry, the effect of various process parameters on weld quality, and the phenomena observed in such welds. The research methodology was based on the analysis of the content of articles from main databases. Apart from capturing the current state of the art, this review evaluates reaching the possible highest joint quality and welding process disadvantages such as porosity, poor surface quality, a tendency toward hot cracking, and low ductility for the Al alloys applied in the automotive industry.

In this study, a 6 mm-thick 6061 T6 aluminum alloy was welded using fiber laser welding, and its mechanical and metallurgical properties were investigated. Full penetration autogenous welds were made at a constant laser power of 4.95 kW using a continuous-wave fiber laser and focal positions of −4 mm. In addition, the shielding gas content was changed for weldments welded at different travel speeds (mm s−1). Accordingly, welding speeds were 50, 40, 35, 25, and 20 mm s−1, and the shielding gas contents were 100% argon (Ar), 10% helium (He) + 90% Ar, 30% He + 70% Ar, 50% He + 50% Ar, and 75% He + 25% Ar. Then, macro and micro images were taken, and some mechanical properties (hardness, tensile test, and bending test) were examined. As a result, the change in shielding gas content and welding speed has provided significant variations in the welding joints. Decreases in mechanical properties were detected due to the coarsening of the precipitates. On the other hand, the narrowness of the weld seam and HAZ obtained in laser welding, compared to traditional welding methods, minimizes this disadvantage.
