Abstract

Resistance spot welding (RSW) is being applied extensively in different industries, specifically the automotive sector. Therefore, this study was conducted to optimize the tensile strength load (TSL) in RSW by investigating the application of dissimilar materials as input parameters. The optimization process involved the combination of different galvanized and non-galvanized steel materials. The production of car bodies using galvanized steel with approximately 13.0 microns thick zinc (Zn) coating was found to be a standard practice, but this zinc layer usually presents challenges due to the poor weldability. This study prepared 27 units of TSL samples using a spot-welding machine and a pressure force system (PFS) for the electrode tip. The aim was to determine the optimal TSL through the exploration of specified RSW parameters. The process focused on using the response surface methodology (RSM) to achieve the desired outcome while the Box-Behnken design was applied to determine the input parameters. The optimal TSL obtained was 5265.15 N by setting the squeeze time to 21.0 cycles at a welding current of 24.5 kA, a welding time of 0.5 s, and a holding time of 15.0 cycles. The highest TSL value recorded was 5937.94 N at 21.0 cycles, 27.0 kA, 0.6 s, and 15.0 cycles respectively. These findings were considered significant to the enhancement of productivity across industries, specifically in the RSW process. However, further study was required to investigate additional response variables such as the changes in hardness and microstructure.
异种金属点焊中的拉伸剪切载荷:响应面法的优化研究
电阻点焊(RSW)被广泛应用于不同的行业,特别是汽车行业。因此,本研究通过研究不同材料作为输入参数的应用,来优化RSW的拉伸强度载荷(TSL)。优化过程涉及不同镀锌和非镀锌钢材料的组合。使用镀锌钢和大约13.0微米厚的锌(Zn)涂层生产汽车车身被认为是一种标准做法,但由于这种锌层的可焊性差,通常会带来挑战。本研究利用点焊机和电极尖端压力系统(PFS)制备了27个单位的TSL样品。目的是通过探索指定的RSW参数来确定最佳TSL。该过程侧重于使用响应面法(RSM)来实现预期结果,而Box-Behnken设计用于确定输入参数。当焊接电流为24.5 kA,焊接时间为0.5 s,保温时间为15.0 cycles,挤压时间为21.0 cycles时,获得的最佳TSL为5265.15 N。最高TSL值为5937.94 N,分别为21.0 cycles、27.0 kA、0.6 s和15.0 cycles。这些发现被认为对提高各行业的生产率具有重要意义,特别是在RSW过程中。然而,需要进一步研究硬度和显微组织变化等其他响应变量。
