摘要:
介绍了轨道车辆高强奥氏体不锈钢材料的焊接性能以及电阻点焊设备的性能特点，分析了单件试件的焊接检验和连续试件的焊接检验中试件的制作方法、检验方法及检验标准。结果表明，只有在外观检测、宏观金相检测、拉伸剪切检测均合格的条件下，才可将点焊设备应用于轨道车辆产品的焊接生产中。
Abstracts:
Welding performance of high strength austenite stainless steel material of rail vehicles and performance characteristics of resistance spot welding equipment are introduced. The specification setting method of test sheet, welding fabrication method of single\|spot welding test and multi\|spot welding test, sampling method of test sample are analyzed. Results show that only under the condition that the spot welding equipment is qualified for appearance test, metallographic test and shear tensile test, can it be approved for rail vehicle product welding and manufacture.
