The resistance spot welding is adopted to joint dissimilar alloys such as aluminum alloy 5052, and low carbon steel alloy 1008. In this work, the electrodes force 2100-2700 N, the welding current 7.5-10.5 KA, and welding time 10-20 cycle have been used. The relationships between the three parameters have been studied. The maximum tensile shear load of the aluminum alloy 5052-low carbon steel 1008 joint has been found equal to 2860 N for weld nugget diameter of 9 mm. The intermetallic compound layer (IMC) with 2-8 μm thickness with tongue-like has been appeared adjacent to the 1008 low carbon steel side, whereas a needle-shaped IMC layer adjacent to the aluminum alloy 5052 side

Aluminum alloy A5052 and low-carbon steel (SPCC) was welded using resistance spot welding with a cover plate. The interfacial microstructure was observed using electron microscopy. A thick two-layered reaction layer contains Fe2Al5 and FeAl3was observed at the welding interface, respectively. Mechanical property analysis suggested that the reaction layer has no effect on the tensile shear strength of the A5052/SPCC joint and affects the cross tension strength of the joint.

This paper describes the development of a computer model used to analyze the heat flow during pulsed Nd:YAG laser spot welding of dissimilar metals; stainless steel AISI 302 to low carbon steel AISI 1008. The model is built using ANSYS FLUENT 6.3 software where almost all the environments simulated to be similar to the experimental environments. A simulation analysis was implemented, based on conduction heat transfer, out of the key hole where no melting occurs. The effect of laser power and pulse duration was studied. Four peak powers 5, 5.5, 6.5 and 7 kW were varied during pulsed laser spot welding (keeping the energy constant), also the effect of four pulse durations 5, 6, 6.5 and 7 ms (with constant peak power), on the transient temperature distribution and weld pool dimensions was predicted ,using the present simulation. It was found that the present simulation model can give an indication for choosing the suitable laser parameters (i.e. pulse duration, peak power) during pulsed laser spot welding of dissimilar metals.
