The Application of Ultrasonic Testing Method for Thin-Diameter Rod

摘要: 本文介绍了用瓦形晶片制作的线聚焦双晶探头,采用水浸法检测直径为5～16mm的高温合金钢的方法及原理,并和超声爬波法相比较.实验结果表明,本方法是较为理想的一种,不仅操作简单,而且能满足技术上的要求.

Abstract: The principle and test method for testing the 5-16mm diameter's rod by tile-shape piezoelectric disc T-R probes and by immersed line-focusing test method is introduced in detail and it is compared with the ultrasonic creeping waves,Thus,the results show that this test method is one of the best methods because it can be operated simply and can meet the technology requirement.
