Long Seam Weld Inspection - Manual and Encoded

Long seam welds can be found in pipelines and other structures such as fume towers, storage vessels etc. Inspection of these welds can be difficult as the curved OD and ID surfaces reflect ultrasonic beams differently depending on the angle of incidence, if this is not accounted for, the results can be positioned incorrectly in the weld and out of sensitivity due to the spreading effect of the curved surface reflections.

The VEO3 uses specialised “Curved surface correction” software to ensure there is adequate sensitivity at the region of interest and that the resulting indications are plotted correctly on the S-Scan.

Single Sided Manual Inspection

Manual inspection of seam welds can be carried out with a single probe setup , either timed scanning or with an encoder.

For a comprehensive package for carrying out manual PA inspection see Package 1 at the end of this document.

Single / Duel sided Semi Automated Inspection

Semi automated scanning can be carried out utilising scanners to position and guide the PA transducers for the full weld inspection. This has the advantage of maintaining a constant probe standoff, fully encoding the scan for accurate defect measurement, and also allows for the use of multiple probe setups to be used simultaneously for quicker inspections.

For a comprehensive semi automated inspection package see Package 2 at the end of this document.
