拼焊板的成形性能不同于单一材料的板料,研究其成形性能有利于改进拼焊板的成形工艺。单向拉伸试验作为一种有效和实用的材料性能测试方法被用于研究拼焊板的成形性能。针对拉伸试验设计了母材和拼焊板的试样并进行了相关试验,获得了不同拼焊板的强度和塑性性能并对结果进行了讨论。试验结果表明,拼焊板的单向拉伸强度介于较高强度母材与较低强度母材之间,但塑性成形性能均低于母材,同时焊接线位置对于其成形性能也有着重要的影响。
Tailored welding plate forming performance is different from a single sheet of material, the study of its formability is conducive to improving the tailor-welded sheet forming process. One-way tensile testing is used as an efficient and practical material property testing method to study the formability of tailor welded panels. Tensile test for the design of the base metal and tailor-welded samples and carried out the relevant tests to obtain the strength and plasticity of the different tailor welded plate and the results were discussed. The test results show that the tensile strength of the tailor welded plate is between the higher strength base material and the lower strength base material, but the plastic formability is lower than the base metal, and the welding line position is also important for the formability Impact.
