流量计焊缝超声检测模拟软件的开发与应用

The development and application of simulation software for ultrasonic testing of flowmeter weld seams

流量计焊缝内部常有未焊透、未熔合等缺陷,应对其进行A型脉冲超声检测,但由于流量计内部结构特殊,单个探头无法满足检测要求,所以需要选用几种不同K值的探头来配合使用。以往采用的K值筛选方法较为繁琐且容易引起误差,因此研究人员采用Visual Studio等开发工具,利用C++语言开发出"流量计焊缝超声检测模拟分析软件",通过该软件可以直观、高效、准确地筛选出满足扫查要求的探头K值组合。

There are some defects in the weld seams of flowmeter,such as incomplete fusion and penetration.There is a need of ultrasonic examination technique using pulse-A mode type ultrasonic testing.However,single probe cannot meet the needs of the examination because of the special structure of the inner flowmeters,and therefore several probes with different K values need to be used.The normal calculating process is labor consuming and easily leading to errors,so a simulation software of using visual studio and C++language is developed for the ultrasonic testing of flowmeter weld seam.It meets the requirements of screening out required probes with suitable K values by the software in an intuitive,high efficient and accurate way.
