RSW Junctions of Advanced Automotive Sheet Steel by Using Different Electrode Pressures

Abstract

Based on this study, the effects of the different types of welding currents and electrode pressures on the tensile shear properties of the resistance spot welding (RSW) which are the joints of the commercial DP600 sheet steel are now been investigated. In addition to the fact that the electrode pressure is not much of a popular piece or topic of discussion in the literature, the expression of the mechanical properties of these commercial materials (most importantly in the DP and in the high strength steels). These factors that are known to be affecting the strength of the material are dispute. In the tensile shear tests of this welded joints; the tensile shear force and the maximum displacement were utilized to characterize the performance of the welding processes. The nugget diameter has been measured to create a clear definition of the RSW physical properties. The experimental results show that the tensile shear load bearing capacity is bond to increase as the electrode pressure increases based on a value in both the welding currents and the decrease at the higher values. The low current value at low and at the highest electrode pressures; during the high current value which could be at the middle of the electrode pressure values it can exhibit the superior mechanical properties. The effect of this electrode pressure on the tensile shear load bearing capacity is bond to increase as the welding current increases as well. This, also been assessed and examined based on the low carbon content.

An Experimental Study of the Influence of Carburizing Treatment Holding Time on the Structure and Hardness of 16NC6 Steel

“…Heat treatment processes can be used to modify the surface and structural properties of low carbon steel in order to have a hard outer surface and a ductile and tough inner core, which is beneficial for engineering applications such as cams, gears, and shafts. These properties assist the resistance in wear and shock, thus extending the life of the component [1][2][3]. Carburizing is an ancient thermo-chemical heat treatment used to harden the surface of low carbon steel by diffusing carbon into it.…”

Effects of welding parameters on tensile properties and failure modes of resistance spot welded DC01 steel

“…This can cause micro-void formation (Figure 4(a)). 35,46,47 EDS analysis was carried out to examine if there were differences in the chemical composition of RSW specimens. Supplementary Figure 11 indicates SEM micrographs taken from specimens that were welded by using 8 kA-1.96 kN and 12 kA-2.94 kN welding parameters, and Supplementary Table 7 indicates EDS results.…”

The Effects of Resistance Spot Welding Parameters on the Mechanical Behavior of Stainless Steel

“…In [18], weld current was the major governing factor affecting the tensile shear strength of resistance spot welded specimens in dissimilar joints formed by stainless steel 304 and galvanized steel, as it presented a high percentage compared to welding time and force. In [19][20], it was shown that using a high welding current, the material can exhibit high mechanical properties, and the tensile shear load-bearing capacity increased as the welding current increased.…”
