saw weld Off-Line Inspection

SOFRATEST provides Ultrasonic inspection solutions for the off-line weld inspection of SAW pipes, outside the production line.

Prior to inspection, the pipe is loaded onto the trolley by the loading arms, allowing it to be transported below the UT control station. The trolley enables the pipe to move forward and spin around. Once the laser detects the weld and and everything is ready,  the inspection process can begin.

Several defects can be detected:

• Internal/External longitudinal and transverse defects detection in the weld (several configurations of probe arrangement are available : I, K, X)
• Lamination defects detection in the Heat Affected Zone (HAZ), in the pipe body and in the ends of the pipe
• Midwall weld defects detection
• Loss of coupling detection

A dynamic calibration can be performed: a standard tube is positioned below the head to allow all settings to be made.

A laser tracking system is available on the Ultrasonic head to follow the weld and enable the probes to adjust their positions themselves.

Phased Array sensors can be seamlessly integrated into the SOFRATEST system.
