The Progress of TOFD Technique in China
Time-of-flight diffraction (TOFD) technique was introduced into China in the start of 21st century. Now there are more than 20 boiler and pressure vessel manufacturers, pressure piping installation companies and inspection agencies or companies engaged in TOFD research and application in China. More than 100 inspectors have been trained and qualified for TOFD. 2 pressure vessel manufacturers and 4 inspection agencies have finished their testing standards. The national testing standard has been drafted. One ultrasonic equipment manufacturer has developed TOFD testing equipment. The research and application fields include equipment developing, TOFD signals analysis and processing, pressure equipment and hydropower station equipment testing, and so on. This paper reviews the history, testing personnel, standards, equipment, research and application area of TOFD in China.
