Orbital Weld Inspection Probes
High-frequency eddy current array probes provide encoded circumferential inspection of orbital welds for submillimeter surface flaws.
Product overview
Orbital Weld Probes use high-frequency eddy current array (ECA) sensing to detect small cracks and surface flaws in orbital welds. Designed as an alternative to liquid penetrant testing, they can scan a tube’s complete circumference in seconds and reduce inspection time by over 90% compared with that method. Including probe attachment, scanning, analysis and reporting, the inspection process can be completed within a few minutes.
A stable clamping mechanism secures the probe around the weld, and the operator rotates it circumferentially to perform the scan. An integrated, lockable encoder contacts the surface, making inspection independent of scanning speed while recording indication positions. Magnifi’s assisted analysis tools support interpretation and reporting of detected anomalies.
The family accommodates different weld diameters while maintaining sensor contact and scanning stability: the smallest probes serve individual diameters, whereas larger probes cover ranges of tube sizes. Standard sensing is optimized for external cracking; custom sensors can be incorporated into the same body for internal or mid-wall defects. Thinner or smaller probe designs can also be built for welds with restricted access.
Key capabilities
High-resolution ECA sensing
High-frequency sensors are optimized for small cracks and submillimeter surface flaws.
Rapid inspection
Inspection time is reduced by over 90% compared with liquid penetrant testing.
Encoded circumferential scanning
An integrated, lockable encoder supports speed-independent inspection and precise indication positioning.
Stable attachment
A clamping mechanism secures the probe around the weld for circumferential scanning.
Compact footprint
The small probe footprint supports inspection of welds with restricted access.
Diameter-specific and range coverage
Small probes serve individual weld diameters, while larger probes accommodate ranges of tube sizes.
Assisted analysis
Magnifi provides assisted tools for interpreting and reporting weld indications.
Customizable sensing and geometry
Custom sensors and thinner or smaller probe bodies can address additional flaw types and restricted weld access.
