Robotic Ultrasonic Inspection for High-Precision Weld Integrity
​
The SAW UT is our most advanced robotic UT inspection system, engineered specifically for Submerged Arc Weld (SAW) pipe production.
Built around an ABB IRB 5720 industrial robot and powered by Sofratest electronics, SAW UT delivers sub-millimetre positioning accuracy and full compliance with API 5L / 5CT and ASTM E273 standards.
​
Designed for demanding mill environments, SAW UT transforms weld inspection from a mechanical challenge into a controlled, data-driven process.
SAW UT Advantages

✔ Designed for HSAW and LSAW Pipe Production
-
Diameter range: 16”–140”
-
Wall thickness: 0.375”–1.5”
-
Helical/Spiral (HSAW) or Longitudinal (LSAW) weld applications
-
8-channel UT system in “IIKK” configuration
-
Longitudinal ID/OD inspection
-
Transverse ID/OD inspection
-
HAZ inspection
-
This configuration ensures full weld coverage for both longitudinal and transverse defect detection.

✔ Weld Profile Measurement and Alignment
SAW UT includes a Keyence weld measurement vision system that:
-
Measures weld height
-
Monitors max weld height alarms
-
Captures weld cross-section data
-
Measures weld width
-
Stores the weld bead profile data
This adds measurable weld-geometry intelligence—not just defect detection.
