Weld examination
Examining accessible weld volumes in fabrication or service where material and geometry are suitable.
PHASED ARRAY ULTRASONIC TESTING (PAUT)
PAUT inspection with planned beam coverage and recorded data.
Phased Array Ultrasonic Testing uses an array of elements with timed excitation to steer and focus ultrasonic beams. Its scan displays help trained personnel assess indications within an agreed examination volume.

Phased Array Ultrasonic Testing (PAUT)
A PAUT setup defines probe, wedge, focal laws, beam angles, scan positions and calibration. Sectorial scans can show multiple angles in a cross-sectional view, while encoded scanning can link the ultrasonic data to distance along a weld or component. The technique and scan plan must demonstrate the coverage needed for the specified inspection objective.
WHERE IT MAY HELP
Potential inspection applications
Component evaluation
Investigating defined areas of piping and other industrial components.
Complementary coverage
Pairing PAUT with TOFD when different sound paths and indication responses are useful under the approved procedure.
Applications are illustrative. Suitability depends on the component and approved inspection procedure.
SCOPE DEVELOPMENT
Information needed for a PAUT enquiry
Send available drawings or specifications with the details below. IAIS can use them to review coverage, calibration, site arrangements and reporting requirements.
01
Component material, thickness and weld geometry
02
Inspection surface, access and scanning clearance
03
Applicable code, examination volume and acceptance criteria
04
Calibration blocks, probe configuration and reporting format
TECHNICAL CONSIDERATIONS
Limits and complementary methods
Beam coverage and resolution vary with the probe, material, geometry and chosen focal laws. Coarse-grained or highly attenuating material, surface condition and restricted access may limit effectiveness. Data interpretation and acceptance remain tied to the approved procedure.
PROJECT ENQUIRY
Discuss the inspection objective.
Share component drawings, applicable code or specification, location and schedule. The team will review the technical basis before proposing a method and execution plan.
