Abstract

This paper presented the test of cup drawing, and the tensile ability of tailor welded blanks (TWBs) used to join the resistance spot welding a variety of different parameters. This study used SPCC-SD (JIS 3141) material with a material thickness of 1.0 mm and 1.2 mm. This research is focused on obtaining the highest tensile-shear strength of resistance spot welding and how it affects the results of the drawing cup process. This study used an experimental research method using six samples of RSW parameters. RSW parameters used are welding current, welding time, and squeeze time. This research was achieved the highest tensile-shear strength value of 5.09 kN and the lowest 4.15 kN which was achieved in the 5th and 1st samples respectively. The results of the cup drawing test using RSW parameters in the 5th and 6th samples showed no TWB failure in the welded area. Further research will be carried out by performing Taguchi optimization using RSW and TWBs parameters in the cup drawing process.

使用不同厚度的钢制钢材对铅焊缝工艺的电阻现位评价

本文介绍了各种不同参数下拼焊板加入电阻点焊的杯形拉伸试验和拉伸性能。本研究采用SPCC-SD (JIS 3141)材料，材料厚度分别为1.0 mm和1.2 mm。研究了电阻点焊的最高抗拉剪切强度及其对拉杯成形效果的影响。本研究采用6个样本RSW参数的实验研究方法。RSW参数为焊接电流、焊接时间、挤压时间。本研究获得的抗剪强度最大值为5.09 kN，最小值为4.15 kN，分别为第5和第1个样品。采用RSW参数对第5和第6个试样进行杯形拉伸试验，结果表明焊区无TWB破坏。进一步的研究将在杯形拉伸过程中使用RSW和TWBs参数进行田口优化。
