摘要

从专业文献中对电阻点焊薄钢板的剪切强度和交叉抗拉强度(STS和CTS)进行了研究。有些方法需要化学成分或焊块强度硬度作为输入参数，在接头规划阶段很难应用。利用从250多篇论文中收集的STS和CTS数据，对选定的相关性进行了测试，以确定它们是否适用于在规划阶段预测RSWed接头的STS和CTS，从而帮助设计人员规划其静载焊接强度。大多数相关性在适用的基材抗拉强度范围内存在局限性。为此，提出了新的STS和CTS方程，可用于在300-18900 MPa范围内规划薄钢异种和相似点焊连接的基本金属抗拉强度。

Global Approach on the Shear and Cross Tension Strength of Resistance Spot Welded Thin Steel Sheets

Several correlations from the professional literature describing the shear and cross tension strength (STS and CTS) of resistance spot welded (RSWed) thin steel sheets were investigated. Some of them need chemical composition or weld nuggets strength hardness as input parameters, making them hardly applicable in the planning stage of the joints. Using STS and CTS data collected from over 250 papers, selected correlations were tested, whether they are applicable to predict the STS and CTS of the RSWed joints at the planning stage to help designers plan their static-loaded welds strength. Most correlations had limitations in the applicable base materials' tensile strength range. Therefore, new equations for STS and CTS are proposed, which can be used to plan in the 300–18900 MPa base metals tensile strength range for similar and dissimilar RSWed joints of thin steel sheets.
