“…There are several recently developed types of CMT welding techniques, namely pulsed advanced CMT [68], advanced CMT, CMT + P, and dynamic CMT [190]. Conventional CMT, pulsed CMT (CMT-P), advanced CMT (CMT-ADV), and pulsed advanced CMT (CMT-PADV) are suitable processes for depositing Al alloy due to excellent performance in controlling porosity.…”

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.
