UT ultrasonic weld runout test

UT ultrasonic weld runout test weld ultrasonic testing of the weld defects are generally divided into three categories: point defects, line defects, planar defects. In the classification of the defect length less than 10mm is called point defects; general accident length less than 10mm by 5mm defect count. The length greater than 10mm defect called linear defects. The length greater than 10mm height greater than 3mm defect called planar defects. Ultrasonic testing thickness 14 mm, the distance measured amplitude curve of three long-term relationship Ф1 х 6 -12dB line is mainly quantitative curve Ф1 х 6 -6dB sentenced degree line Ф1 х 6 -2dB 1, no defects bottom wave only multiple reflections waves. 2, no more defects bottom wave only wave disorder. 3, defect wave and the end of wave exist.
