Resistance Spot welding is low cost and adequate which has made it highly popular in the making of sheet joints. Various types of resistance welding are developed for producing continuous and pressure tight joints on overlapped materials. Controlling the welding parameters plays an important role in the quality of the weld. This paper reviews on various effects of process parameters on response variables. Input parameters such as welding current, weld time, electrode force and electrode geometry effects on the response variables such as tensile strength, hardness, nugget size. In any automobile, there are 3000-6000 spot welds which demonstrate the level significance of the resistance spot welding. Controlling the welding parameters assumes an imperative part on the nature of the weld.Quality and strength of the welds and therefore body mainly are defined by quality of the weld nuggets. Resistance Spot Welding (RSW) is widely used for its low cost, high speed; simple mechanism and applicability for automation. There are various process parameters (weld current, weld time, pressure) which affect the weld nugget and its strength. So it is necessary to optimize the process parameters of resistance spot welding process. Therefore it is very important to understand the behaviour of spot welds and their failure characteristics.

“…The standard also mentions the possibility of deviation of reduction factor for HAZ of prescribed alloys due to possible small differences in chemical composition of the same alloy depending on the manufacturer. The influence of welding is still the subject of a considerable number of experimental and numerical investigations [59][60][61][62][63][64] (Table 3) because of its effect on the stability and some favourable properties. This influence is additionally studied [65,66] with the introduction of new welding methods such as friction stir welding (FS -friction stir), which has a similar effect on the base material.…”

Although aluminium is a structural material that has been present on the market for a long time, its use is not in accordance with the benefits that can be achieved by its application. While it is similar to steel, there are significant differences between these materials, both in manufacturing and in physical and mechanical properties. Due to such differences, these materials exhibit distinct features in the areas of cross sectional and elements stability and welds. These areas are still an active field of research due to a large number of alloys, processing methods, and cross-sectional shapes. Stanje područja stabilnosti i zavarivanja elemenata od aluminijskih leguraIako je aluminij već dugo prisutan konstrukcijski materijal, uporaba mu nije u skladu s dobrobitima koje se ostvaruju njegovom primjenom. Sličan je čeliku, no između njih postoje značajne razlike kako u proizvodnji, tako i u fizikalnim i mehaničkim svojstvima. Upravo iz tih razlika proizlaze posebnosti u područjima stabilnosti dijelova poprečnih presjeka i konstrukcijskih elemenata te u područjima zavara. Ta polja još uvijek predstavljaju aktivna područja istraživanja zbog velikog broja legura, obrada i oblika poprečnih presjeka profila.

“…Han et al. 15 applied a statistical model to study several forms of evaluating the mechanical strength of RSW joints. Darwish SM and Al–Dekhial SD 16 introduced response surface methodology to analyze the influence of process parameters (welding current, weld time, electrode force and sheet thickness) on the strength of spot-welded BS 1050 commercially pure aluminum sheets with different thickness (0.5 mm, 1 mm, 1.5 mm, 2 mm, 2.5 mm).…”

Evaluating the strength performance of spot-welded joints of dissimilar material is critical for their continued integration into the automobile and aerospace industries. The effect of weld joint strength is an important consideration in the design of weld structures. The objective of the present work undertaken to investigate the effect of the input process parameters on the strength of the welded joint of dissimilar material. Full factorial design (FFD) has used for designing the experiment matrix. Further, experimental results have used to develop a mathematical model to predict the strength of the spot weld joint. Analysis of Variance (ANOVA) has been applied to establish the correlation between the process parameters and their interaction on the output. The confirmation test case experiments have conducted for validating the developed mathematical model and observed that the developed model is capable of evaluating weld joint strength within the process parameters.
