Off-Line Weld Inspection


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

  • Internal/External longitudinal and transverse defects in the weld (with several configurations of probe arrangement are 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 functionning of the system, the loss of coupling is also detected.

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

For calibration, 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 track the weld and allow the probes to adjust their positions.

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

Customization of the test heads is also possible to allow inspection of the pipe ends.

SOFRATEST can provide probe holders that oscillate between two welding zones to inspect the pipe body.

Our equipment is adaptable based on the diameter, thickness, and length of the pipe, enabling a 100% inspection of the product.


With our robust and user-friendly software, the results of the Ultrasonic inspection are displayed in real-time.

Traceability is ensured by our production software, creating comprehensive and customizable inspection reports.

The system screen is accessible remotely, providing a clear, global view of the ongoing inspection and allowing necessary adjustments to be made in real-time.
