“…The main effect plot, Fig. 6a, displayed that the shear force of the joint increases by increasing the plunging depth of the tool and decreasing the pre-heating time [23]. This can be due to the fact that an increase in the plunging depth can increase the interlock at the joint surface between the two materials with the aid of the applied pressure of the tool.…”

This work aims to join sheets of carbon steel to aluminum alloy AA6061. A lap joint arrangement was used with a joint lap area of dimensions * 25 25 mm. The joining procedure was carried out using a rotating tool of 10 mm shoulder diameter. Three process parameters, with three levels for each parameter, were selected to investigate their effects on joints quality. The parameter’s levels for each experiment were designed using the design of the experiment method (DOE). The results indicated that the two materials were joined by a mechanical interlock at an interface line, without formation of intermetallic compounds. The shear force of the joint reached an ultimate value of. 482kN. The shear force of the joint improved by increasing plunging depth of the tool. Samples of minimum shear force value failed by a pull-outing aluminum metal from the carbon steel specimen. Samples of higher shear force value exhibited a shear mode of fracture. Increasing the rotating speed and decreasing pre-heating increased the process temperature.

“…However, there is no clear understanding of the underlying mechanisms since it may also depend on other process parameters and conditions. For FSW with low heat inputs, the critical thickness of 0.5-0.7 µm was identified [104,105], where, below this value, high tensile strength is achieved, comparable to base metal strength; see Figure 12a. With the IMC thickness of >0.7 µm, a sharp decrease in strength occurs [105].…”

Modern industry requires different advanced metallic alloys with specific properties since conventional steels cannot cover all requirements. Aluminium alloys are becoming more popular, due to their low weight, high corrosion resistance, and relatively high strength. They possess respectable electrical conductivity, and their application extends to the energy sector. There is a high demand in joining aluminium alloys with other metals, such as steels, copper, and titanium. The joining of two or more metals is challenging, due to formation of the intermetallic compound (IMC) layer with excessive brittleness. High differences in the thermophysical properties cause distortions, cracking, improper dilution, and numerous weld imperfections, having an adverse effect on strength. Laser beam as a high concentration energy source is an alternative welding method for highly conductive metals, with significant improvement in productivity, compared to conventional joining processes. It may provide lower heat input and reduce the thickness of the IMC layer. The laser beam can be combined with arc-forming hybrid processes for wider control over thermal cycle. Apart from the IMC layer thickness, there are many other factors that have a strong effect on the weld integrity; their optimisation and innovation is a key to successfully delivering high-quality joints.

“…In order to prevent the deterioration of the dissimilar joint quality, it is necessary not only to decrease the IMC layer thickness to a few micrometers or less, but also to reduce the heat input to suppress the formation of the softened heat affected zone (HAZ). Accordingly, various solid-state welding methods, such as friction stir welding, [13][14][15][16][17][18] friction stir spot welding [19][20][21] and friction welding, [22][23][24][25][26][27] have been used for dissimilar joining of Al and Fe combinations. Fukumoto et al 13) reported that the material flow of both sides in the friction stir butt welding between Al alloy and steel is the most influential factor on the joint's microstructure and mechanical properties.…”

The effect of weld parameters on the microstructure and mechanical properties of AA5052/S45C dissimilar joints fabricated by a novel pressure-controlled joule heat forge welding (PJFW) was systematically investigated. The deformation behaviors of the materials during the welding process were able to be controlled by regulating the electrical resistance which affects the heating rate. Since the welding temperature decreased with the increasing applied pressure, the formation of the intermetallic compounds layer at the weld interface was suppressed. Thus, a peak joint efficiency of 85% was reached by applying a high pressure of 180 MPa.
