PAUT Weld Inspection Services

This platform is specially developed to present our dedicated PAUT inspection services, and weld inspection remains one of the most important and widely applied areas within our service portfolio. Our PAUT weld inspection solutions are designed to support quality assurance, fabrication control, condition monitoring, in-service evaluation, and fitness-for-service decision-making for critical welded components.

By combining practical field experience, advanced inspection capability, and a strong understanding of industrial assets, we help clients maintain safety, compliance, reliability, and operational continuity through dependable weld inspection services.

What Is PAUT Weld Inspection?

Phased Array Ultrasonic Testing (PAUT) is an advanced ultrasonic inspection technique used to examine welded joints for internal and surface-connected discontinuities. Unlike conventional ultrasonic testing, PAUT uses multiple elements and beam steering capabilities to inspect welds from different angles and focal depths, allowing improved detection, sizing, and characterization of flaws.

PAUT weld inspection is highly effective for identifying and evaluating indications such as:
➤ Lack of fusion
➤ Lack of penetration
➤ Cracks
➤ Slag inclusions
➤ Porosity clusters
➤ Volumetric indications
➤ Root-related discontinuities
➤ Sidewall fusion defects
➤ Heat-affected zone related flaws

This technique is widely used for both new fabrication inspection and in-service weld assessment, particularly where accuracy, traceability, and coverage are critical.

Our PAUT Weld Inspection Capability

At NDT AND PWHT Solutions Pvt Ltd, our PAUT weld inspection services are planned and executed with a practical engineering approach based on the component geometry, weld configuration, access limitations, material condition, and project requirements.

Fabrication Weld Inspection

Inspection of newly fabricated weld joints to verify quality, workmanship, and compliance with project or code requirements before commissioning or handover.

In-Service Weld Inspection

Assessment of weld condition during operation or shutdown to detect service-induced degradation, crack development, or integrity concerns.

Repair Weld Validation

Post-repair examination to confirm the soundness of repaired weld joints and support acceptance prior to return to service.

Critical Weld Integrity Assessment

Evaluation of safety-critical welds in high-temperature, high-pressure, cyclic, or corrosive environments where weld reliability is essential.

Shutdown and Turnaround Inspection

Fast and dependable inspection support during shutdowns where weld evaluation must be completed within limited time windows.
