本实验目的是评价声发射技术检测16Mn钢焊接缺陷的能力。通过带各种缺陷试样拉伸试验声发射监测的试验结果表明:声发射技术能在材料屈服前检测出16Mn钢中大尺寸和尖锐形状的焊接缺陷声发射技术对于检测严重焊接缺陷是有效的。 The purpose of this experiment was to evaluate the ability of acoustic emission techniques to detect welding defects in 16Mn steel. The results of the acoustic emission monitoring tests on tensile specimens with various defects show that acoustic emission techniques can detect large and sharp weld defects in 16Mn steel prior to yielding. Acoustic emission techniques are effective in detecting severe weld defects .
