A new technique of thermal compensation resistance spot welding was used to weld light metal such as aluminum alloy sheet and magnesium alloy. The effects of welding parameters on the tensile shear strength of joint and nugget diameter were investigated. The tensile shear load and nugget of the joint increased with the increasing of welding time, whereas that of the joint decreased with the increasing of electrode force. The joint with the maximum tensile shear load of approximately 5 kN was obtained at the condition of 12 kA and 11 kA welding current for aluminum alloy and magnesium alloy, respectively. The results reveal that the thermal compensation resistance spot welding is a feasible method to weld aluminum alloy and magnesium alloy..

Expulsion is undesirable during the resistance spot welding due to the weld quality decrease. The expulsion happening during the resistance spot welding of AZ31B magnesium alloy was studied related to the distribution of maximum temperature in the interface due to the existing of contact resistance, and connected with the increased pressure in the nugget due to melting and expansion of liquid metal. The influence of welding parameters on expulsion is presented and discussed in this investigation.

In order to obtain better understanding of the resistance spot weldability of magnesium alloy and provide some foundational information for improving mechanical properties of the magnesium alloy joint, the influencing factors of pore formation during resistance spot welding of magnesium alloy, such as preexisting pores in base material, hydrogen rejection, shrinkage strain and expulsion, were analyzed; the corresponding restraining measures were discussed. The analyses reveal that the shrinkage strain and expulsion are important factors in contributing to the formation of pores during resistance spot welding of magnesium alloy, and that the pore formation could be suppressed by adjusting welding parameters.

Abstract Resistance spot welding (RSW) was applied to non-combustible magnesium alloy, AX41 (Mg-4%Al-1%Ca) to investigate its weldability. The similar material joint of AX41 and dissimilar materials joint between AX41 and aluminum alloy, AA6061 were welded. Tensile shear test was carried out to evaluate joining strength in the similar and dissimilar materials RSW joints. In case of similar material joints, the maximum load obtained with tensile shear test in AX41 similar material joint was higher than that obtained in AA6061 similar material joint. Moreover, higher maximum load was obtained in a similar material joint without surface polishing compared to joint welded with surface polishing in AX41. In case of the dissimilar materials joint, the maximum load obtained was almost comparable with AX41 similar material joint, however scatter in joint strength was large. Weldability of the dissimilar materials joint became poor by applying surface polishing.

Abstract In the present research, a digital twin of coaxial one-side resistance spot welding (COS-RSW) was established for the real-time prediction of transient temperature field. A 3D model of COS-RSW joint was developed based on the in-house finite element (FE) code JWRIAN-SPOT. The experimental verified FE model was employed to generate the big data of temperature of COS-RSW process. Multiple dimension interpolation was applied to process database and output prediction. The FE model can predict the thermal cycle on COS-RSW joints under different parameter couples. The interpolation effect of individual welding parameters was discussed and a power weight judgement for welding time was essential to ensure accuracy. With the support of big data, the digital twin can provide visualization prediction of COS-RSW within 10 seconds, whereas numerical modelling needs at least 1 hour. The proposed application of digital twin has potential to improve the efficiency of process optimization in engineering.
