Off-Line Weld Inspection

SOFRATEST provides Ultrasonic inspection solutions for off-line weld inspection of ERW pipes, outside the production line. Various types of defects are detected, including:

• Internal/External longitudinal defects and transverse defects in the weld (several configurations of probe arrangements available: I, K, X)
• Lamination defects in the Heat Affected Zone (HAZ), in the full body, and in the ends of the pipe
• Different kinds of defects in the middle of the weld

To ensure the proper functioning of the system, the loss of coupling is also detected.

SOFRATEST’s designed inspection head perfectly adapts to the different curvatures and diameters of the pipes.

The inspection head can slide to a standard pipe positioned on a calibration support to perform calibration.

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

The control system can automatically adjust itself in case of deviation of the area to be controlled from the inspection head, thanks to the presence of a pilot line tracking system.

An additional function allows the rotation of the ERW pipes, resulting in a complete inspection of the pipe body.
