Ultrasonic welding inspection device

In the last several years, automated ultrasonic testing (AUT) has begun overtaking traditional radiography as the pipeline weld inspection method of choice throughout the world. Radiography has significant limitations: poor detection of planar defects, no vertical sizing capability, safety issues, and environmental concerns.

The advantages of AUT:

- No radiation hazard, no chemicals, no licensing
- Very short inspection cycle time for high production rate
- Better detection and sizing accuracy, leading to lower rejection rate
- Use of Engineering Critical Assessment (ECA) acceptance criteria with measurement of vertical height and depth of indications, reducing rejection rate
- Real-time analysis from smart output display
- Data and inspection reports on electronic support
- Better control of welding process, also giving lower rejection rate
