Robotic Ultrasonic Inspection for High-Precision Weld Integrity
​
The IRBUT 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, IRBUT delivers sub-millimetre positioning accuracy and full compliance with API 5L / 5CT and ASTM E273 standards.
​
Designed for demanding mill environments, IRBUT transforms weld inspection from a mechanical challenge into a controlled, data-driven process.
IRBUT Advantages
Designed for SSAW and LSAW Pipe Production
-
Diameter range: 16”–140”
-
Wall thickness: 0.375”–1.5”
-
Circumferential or Spiral SAW 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
IRBUT 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.
