摘要
针对高压薄壁焊接钢筒工件的内部质量检测问题,通过对五种常规无损检测方法的比较,确定了采用超声波板波法的优点.本介绍了板波的原理、特点、速度与入射角的关系、模式的能流分部并绘制了能流分部图.以高压薄壁焊接钢筒检测为例进行了现场试验,并以X射线检测复测来确认板波检测的可靠性,对比试验结果证明,超声波板波法可有效的发现高压薄壁焊接钢筒焊缝内部缺陷,并可实现快速在线检测,具有广阔的应用前景.
Aim at the problem of internal quality testing of high-pressure thin-wall welded steel cylinder pipe workpiece,the advantages of the method of using ultrasonic plate wave are obtained through the comparison of five general nondestructive testing methods by the paper.The theory、characteristics、the relation between velocity and incidence angle、the energy flow distribution of mode are given in this paper.In addition,energy flow distribution chart is also plotted.Taking an example of the testing of high-pressur...
