ON-LINE WELD SEAM UT
Function
- Production monitoring after welding process
- Stable & rigid test mechanism for on-line condition
- Conventional multi-ch. or advanced phased array technique
- Optional bead monitoring
PERFORMANCE
- Coupling
- Water-column
- Frequency
- 3.5 ~ 5 MHz
- Flaw
- Longitudinal flaw at weld seam with coupling check
Option : Laminar flaw in HAZ
- Test method
- Pulse echo
C.V or P.A UT technique
- Flaw Detectability
- N5 notch (or 1.6mm TDH)
- Seam-tracking
- Conventional UT : Manual tracking
Phased array UT : without seam-tracking
