渗透检测A型试块的加工、检验及质量对比

Processing,inspection and quality comparison of A-type test block for penetrant testing

A型试块在渗透检测中使用范围较广,可用于检验渗透检测剂质量,比较两种渗透检测剂的优劣,以及鉴定非标准温度下的渗透检测方法。介绍了渗透检测A型试块的制作方法(包括可控非均匀加热装置、非均匀散热冷却处理装置)、检验及质量对比等。

A-type test block is widely used in penetrant testing.It can be used to test the quality of penetrant testing agents,compare the advantages and disadvantages of two penetrant testing agents,and to identify penetrant testing methods at non-standard temperatures.The article introduces the production and quality control of A-type test block for penetrant testing,which includes controllable non-uniform heating device and non-uniform cooling device.
