In AUT of pipeline girth welds a series of probes or a phased array probe is mounted on a band strapped around the pipe adjacent to the weld and is driven around the pipe's circumference. As the probe(s) travel around the pipe, ultrasonic data is collected from the weld and the software enables flaw sizes and positions to be displayed. Very fast scanning speeds (~100mm/s) are called for, since, to keep pace with construction, it is necessary to complete a weld inspection every 2-4 minutes. AUT is replacing radiography for pipeline girth weld inspections worldwide. The advantages of conventional AUT over radiography are:
Ultrasonic personnel engaged in the testing of girth welds for onshore and offshore pipelines.
10 days (80 hours) including examination.
Candidates with good knowledge over Ultrasonic Testing & its application may enroll towards this program, if the interested candidates doesn't have enough knowledge over Ultrasonic Testing and it’s practical application, those candidates may initially enroll towards Practical Ultrasonic Testing/ Specialization in A- Scan UT program conducted at Decibel and after that they can enroll towards this program.
