超厚爆炸复合板结合面隐性缺陷分析及检测

Recessive Defect Analysis and Testing of Bonding Surface for Ultra-thick Explosion Clad Plate

为分析超厚爆炸复合板结合面隐性缺陷性质及危害性,对304L+SA516Gr70复合板取样进行金相试验、拉伸试验及剪切试验,通过试验结果判定复合板结合面隐性缺陷的特性及危害程度。结合现有复合板的检测方法及复合板缺陷特性,制定对该类缺陷具有针对性的检测方法,以确保超厚复合板的质量及其设备安全性。

In order to analysis the nature and harmfulness of recessive defect in bonding surface of ultra- thick explosion clad plate, we take 304L ＋ SAS16Gr70 samples to perform metallographic test, tensile tests and shear tests, and by comparative analysis of the test results to find the defect characteristics and harmfulness. Combined with the existing testing standards and the defect characteristics, to determine testing method of such defects, to ensure the quality of the clad plate and equipment.
