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

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.
