Certified Ultrasonic Weld Testing in Guyana – UT Services by Qualitest

Delivered by Qualitest Offshore Inc.

Qualitest Offshore Inc. offers highly accurate Ultrasonic Weld Testing (UT) services across both onshore and offshore facilities throughout Guyana. Our skilled inspectors use advanced ultrasonic equipment to detect internal weld defects in pipelines, pressure vessels, structural steel, and fabricated components across industries such as oil & gas, marine, construction, and power generation.

🔍 What is Ultrasonic Weld Testing (UT)?

UT is a non-destructive testing (NDT) method that uses high-frequency sound waves to detect subsurface defects within a weld. These sound waves reflect off imperfections such as cracks, lack of fusion, or porosity, which are then analyzed by certified technicians to ensure weld integrity.

UT is widely trusted for its precision, portability, and safety—requiring no radiation and offering immediate defect detection during or after welding.

🔍 Reliable UT Weld Inspection for Pipelines and Pressure Vessels in Guyana

Ultrasonic Weld Testing is a non-destructive testing (NDT) technique that uses high-frequency sound waves to locate internal flaws in welds. This method ensures the structural integrity of welded joints by identifying issues such as cracks, lack of fusion, porosity, and inclusions—all without damaging the component.

⚙️ Why Choose UT for Weld Inspection?

✔ Accurate detection of internal discontinuities
✔ Immediate results without the need for film processing (unlike radiography)
✔ Safe—no radiation exposure involved
✔ Portable and cost-effective for field and fabrication shop use
✔ Suitable for all weld configurations (butt, fillet, T-joints, etc.)
✔ Fully traceable data and digital reporting
✔ Compliant with major international codes and standards

🛠️ UT Inspection Process

1. Surface Prep
   Weld surfaces are cleaned to remove coatings or debris that may affect signal transmission.
2. Couplant Application
   A liquid medium (couplant) is applied to allow efficient ultrasonic energy transfer.
3. Probe Scanning
   Technicians scan the weld area using calibrated ultrasonic probes.
4. Signal Analysis
   Echoes from flaws are displayed on a screen and interpreted in real time by certified personnel.
5. Defect Evaluation & Reporting
   We record the location, size, and type of flaws and provide a digital report with recommendations if needed.
