“…The reduction in fuel consumption can be achieved by utilizing aluminum or magnesium alloys in different parts of vehicle. In these circumstances and by substituting steel components with aluminum, the low density of aluminum can be an effective solution [1]. Recently, substantial work has been reported about the welding-brazing process for dissimilar metal joining.…”

In this research, the galvanized steel with thickness of 2 mm was joined to the 5754 aluminum alloy with thickness of 3 mm by the cold metal transfer MIG welding-brazing process. The effect of the filler wires (AlSi 3 Mn, AlSi 5 , and AlSi 12 ) and wire feed speeds (4.7, 5, and 5.3 m/min) on metallurgical and mechanical properties have been discussed. According to the experimental results, thickness of intermetallic compound (IMC) layer which was formed along the interface during the MIG welding-brazing was varied by changing of parameters. In addition, the results indicated that by increasing of the wire feed speed, the thickness of IMC layer at first decreased and then increased. Results indicated that the maximum thickness variation of IMC layer belonged to the AlSi 12 filler wire and the best consistent tensile strength was produced with AlSi 3 Mn filler wire with an average value of 188 N/mm 2 . Observation of the failed specimens indicated two types of failure modes under the tensile load, including the fractures occurred in HAZ of aluminum and the fractures occurred near IMC layer.

“…It was found that the morphology of interface layer changed from ser-rated shape to tongue-like shape with the increase of weld heat input as well as the thickness of the interface layer increased. In addition, there are a lot of researches on cold pressure welding (CMT), 13,14) laser welding, [15][16][17] resistance spot welding (RSW) 18,19) and friction welding (FW) 20,21) to investigate the microstructure of interface layer and improve the mechanical properties of weld joints.…”

“…With the laser keyhole-welding technique, rather good mechanical properties were obtained by irradiating steels placed on Al sheets, and limiting Al to steels mixed with a reduced steel penetration in Al alloys [8]. This indicates that the laser keyhole welding process was mainly used to lapped or overlapped joints [12,13,15,[22][23][24]. It can be, but rarely is, used for welding Al/steel butt joints requiring accurate groove preparations, flux and filler wires [24][25][26][27].…”

Dissimilar Al/steel butt joints of 6.0 mm thick plates have been achieved using fiber laser keyhole welding autogenously. The cross sections, interface microstructures, hardness and tensile properties of Al/steel butt joints obtained under different travel speeds and laser beam offsets were investigated. The phase morphology and thickness of the intermetallic compound (IMC) layers at the interface were analyzed by scanning electronic microscopes (SEM) using the energy-dispersive spectrometry (EDS) and electron back-scattered diffraction (EBSD) techniques. The results show that travel speeds and laser beam offsets are of considerable importance for the weld shape, morphology and thickness of IMC layers, and ultimate tensile strength (UTS) of Al/steel butt joints. This proves that the IMC layers consist of Fe 2 Al 5 phases and Fe 4 Al 13 phases by EBSD phase mapping. Increasing laser beam offsets from 0.3 mm to 0.7 mm significantly decreases the quantity of Fe 4 Al 13 phases and the thickness of Fe 2 Al 5 layers at the interface. During tensile processing, the Fe 2 Al 5 layer with the weakest bonding strength is the most brittle region at the interface. However, an intergranular fracture that occurred at Fe 2 Al 5 layers leads to a relatively high UTS of Al/steel butt joints.
