“…There are numerous papers concerning the FSSW parameters which affect the joint geometry and the weld strength [16,29,30]. The quality of a spot weld is usually determined by a lap-shear test [31]. Standard lap-shear tests are used to find the joint strength of a resistance spot weld [32].…”

Abstract. The effects of tool geometry and properties on friction stir spot welding properties of polypropylene sheets were studied. Four different tool pin geometries, with varying pin angles, pin lengths, shoulder diameters and shoulder angles were used for friction stir spot welding. All the welding operations were done at the room temperature. Lap-shear tensile tests were carried out to find the weld static strength. Weld cross section appearance observations were also done. From the experiments the effect of tool geometry on friction stir spot weld formation and weld strength were determined. The optimum tool geometry for 4 mm thick polypropylene sheets were determined. The tapered cylindrical pin gave the biggest and the straight cylindrical pin gave the lowest lap-shear fracture load.

“…The physical welding attributes such as fusion zone size, weld penetration and electrode indentation are the most important parameters governing the mechanical performance of resistance spot welds. It has been shown that weld current and weld time significantly affect these characteristics [17]. For instance, volume of melted metal is a function of heat input which is governed by the welding parameters including weld current and weld time.…”

“…Welding time, welding current and load applied on the electrode prior to transmitting the welding current exhibit important effects on mechanical properties due to their influence on current flow [5]. An increase in weld current and heat input increased the failure load of spot welds on carbon and stainless steels, aluminum and magnesium alloys [3,[6][7][8]. The shear strength of a single lap spot welded joint is a complex phenomenon, which depends on several factors, namely, welding parameters and base metal properties [9,10].…”

“…The shear strength of a single lap spot welded joint is a complex phenomenon, which depends on several factors, namely, welding parameters and base metal properties [9,10]. The main failure modes for static weld strength using lap-shear are cross-nugget and complete button pull-out failure [8,11]. In the cross-nugget failure mode, failure occurs via crack propagation through the nugget fusion zone (FZ), while in complete button pull-out mode, the failure occurs via complete nugget withdrawal from one sheet.…”

In this research, the effect of spot welding parameters on weld quality was investigated. The main affecting welding parameters such as weld current, weld time, electrode force and holding time were determined as the basis for quality evaluation. The selected quality features were classified into mechanical properties and failure behavior, which were required for application with highly dynamic loading. The peak load as one of the important mechanical properties, as well as the two distinct failure modes which were cross-nugget and complete button pull, were observed using tensile-shear stress. To obtain detailed shear stress testing results and to determine the significance of parameters, a servo-hydraulic testing machine was run at a constant cross-head speed of 2mm/min followed by statistical analysis methods, which were Taguchi's L 16 orthogonal array and Analysis of Variance (ANOVA). Furthermore, the failure mode was to be observed based on the fracture surface used as reference for acceptance or rejection of the weld joint. Based on the results, the weld current was the significant factor affecting shear stress and the complete button pull was mostly found, which leads to the satisfactory condition of the joint. Cross-nugget and full button pull-out were the dominant failures observed in the lap-shear test. The cross-nugget failure leads to a low shear load, while complete button pull-out displays maximum shear load.
