Real-time multiple technologies scanning for weld seam geometry, undercut detection, reinforcement height, porosity, and misalignment on ERW, HFI, LSAW, and spiral weld pipes.
±0.02 mm accuracy | 100% coverage | Real-time pass/fail
When pulsed eddy current fails, this system delivers. Designed for challenging welds where conventional methods produce unreliable or very bad results, it provides exceptional robustness and micron-level precision. The technology ensures long-lasting control by detecting macroscopic defects, monitoring scarfing quality, and revealing internal flaws with X-ray TDI sensors. Unlike eddy current techniques that struggle with surface conditions or material variations, this solution operates flawlessly even in harsh environments. For pipelines, flat metals, and coil joining, it guarantees excellent, repeatable weld assessment you can trust for zero-defect production.
Scarfing operation removes excess weld bead to match the non‑welded profile, making the weld invisible.
⚠️ Flaws possible: excessive removal (too deep) or insufficient removal (residual bead).
UT Scarfing Monitor — ultrasonic device scans the weld zone, checks quality of material removal.
Laser profilometers · 3DS system — complete solution for checking external shape and weld bead dimensions.
⚡ Extremely fast online inspection with latest‑gen linear laser scanners → reconstructs weld area shape down to micron level.
✅ Highlights macroscopic defects, ensures dimensional accuracy.
X‑ray technology · WeldAn system uses TDI sensors + X‑ray to detect internal weld defects.
🎯 Specifically designed for small‑diameter, thin‑walled pipes — operates in‑line during production.
💪 Highly robust: functions flawlessly even in very harsh environments.
Complete solution for external shape & weld bead dimensions. Ultra‑fast inline inspection with linear laser scanners → micron‑level reconstruction of the weld area → macroscopic defect detection.
