CSWIP3 - TWI EN 473 Certification Course for Automated Ultrasonic Testing (AUT) Technicians

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:

  • No radiation hazard.
  • Better process control of welding, giving lower reject rates.
  • Larger defect acceptance using Engineering Critical Assessment (ECA), also giving lower reject rates.
  • Faster inspections.
  • Rapid and reliable data interpretation from special output display.
  • Overall, mechanized ultrasonics offer a better inspection solution with lower reject rates than radiography.

Instruction in phased array technique; advantages/disadvantages; in-depth coverage of PipeWizard or similar system; equipment, interpretation of results; troubleshooting etc.

Objectives

  • To set up and operate AUT scanners
  • To configure software for differing weld configurations
  • Calibration of equipment

Suitable For

Ultrasonic personnel engaged in the testing of girth welds for onshore and offshore pipelines.

Duration

10 days (80 hours) including examination.

Additional Information

Available to companies with automatic phased array equipment. Certified by CSWIP. Eclipse can also work to customize the course
content to accommodate the girth weld inspection system you use to ensure staff are fully aware of your selected inspection system's
capabilities.

Entry Requirements

Course candidates must be qualified to a minimum of EN 473 or ISO 9712 (CGSB) Level 2 Ultrasonic Testing.
CSWIP certification is available for candidates holding ASNT UT Welds. It will be considered on an individual basis and evidence of training and experience presented to the training centre on application. Additionally, holders of ASNT UT Welds qualification will be required to sit the CSWIP UT Welds Level 2 General Paper.
