On-Line Weld Inspection

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

• Internal/External longitudinal and transverse defects in the weld (several configurations of probe arrangement are available : I, K, X)
• Lamination defects in the Heat Affected Zone (HAZ) of the weld
• Different kind of defects in the middle of the weld

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

The design of SOFRATEST inspection heads adapts perfectly to the different diameters of the pipes.

When necessary, the inspection head can slid to an off-line position to perform a calibration on a standard pipe.

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

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