Ultrasonic Testing (UT)

Ultrasonic Testing (UT) is a highly reliable non-destructive testing (NDT) method used to detect internal flaws in welds, such as cracks, voids, and inclusions. Using high-frequency sound waves, UT allows us to evaluate the integrity of weld joints without causing any damage to the material. This method is especially valuable for inspecting critical welds in pipelines, pressure vessels, and structural components where safety and compliance are essential. Our certified technicians utilize advanced ultrasonic equipment to deliver accurate and detailed inspections in accordance with industry standards such as ASME, AWS, and API codes.

Radiographic Testing (RT)

Radiographic Testing (RT) is a proven non-destructive testing method used to examine the internal structure of welds for hidden defects such as porosity, slag inclusions, lack of fusion, and cracks. By using X-rays or gamma rays, RT provides a permanent visual record of weld quality, making it ideal for critical applications in industries like oil & gas, construction, and pressure vessel fabrication. Our certified inspectors interpret radiographic images in compliance with applicable codes and standards (such as ASME, API, and AWS), ensuring that your welds meet the highest levels of safety, reliability, and regulatory compliance.

Eddy Current Testing (UT)

Eddy Current Testing (ET) is an advanced non-destructive testing method used to detect surface and near-surface flaws in conductive materials without the need for direct contact. Ideal for inspecting welds, heat-affected zones, and corrosion-prone areas, ET uses electromagnetic induction to identify cracks, pits, or material thinning. This method is highly effective for complex geometries and fast, reliable inspections with minimal preparation. Our certified technicians perform eddy current testing in accordance with industry standards, providing accurate results and ensuring structural integrity in critical components.

Infrared Thermography (IR)

Infrared Thermography (IR) is a non-destructive testing technique that uses thermal imaging to detect anomalies in welded structures by measuring surface temperature variations. This method is particularly effective for identifying issues such as subsurface cracks, lack of fusion, or overheating during welding processes. IR testing provides real-time, non-contact analysis, making it ideal for high-temperature or hard-to-reach components. Our certified inspectors use advanced infrared cameras to perform thorough thermal assessments, helping ensure weld quality, process control, and early detection of potential failures.

Acoustic Emission Testing (AE)

Acoustic Emission Testing (AE) is a dynamic non-destructive testing method used to monitor the release of energy from localized sources within materials under stress. During welding inspections, AE can detect the formation and growth of cracks, weld failures, or structural degradation in real time, often while the component is in service. This technique is especially useful for evaluating large or complex structures such as storage tanks, pressure vessels, and pipelines. By capturing high-frequency sound waves emitted from active flaws, our certified inspectors can assess the integrity of welded components and provide early warning of potential failures, ensuring safety and reliability.

Phased Array Ultrasonic Testing (PAUT)

Phased Array Ultrasonic Testing (PAUT) is an advanced ultrasonic inspection technique used to detect internal flaws and assess weld quality with high precision. By utilizing multiple ultrasonic elements and electronically controlled timing, PAUT can create detailed cross-sectional images of welds and materials. This allows for accurate detection of defects such as cracks, lack of fusion, and porosity, even in complex geometries. PAUT is ideal for critical applications in industries like oil & gas, power generation, and aerospace. Our certified technicians use state-of-the-art equipment to deliver efficient, reliable, and code-compliant inspections in accordance with ASME, API, and AWS standards.

Time Of Flight Diffraction (TOFD)

Time of Flight Diffraction (TOFD) is a highly accurate ultrasonic testing technique used for detecting and sizing flaws in welded joints. Unlike conventional UT methods, TOFD relies on the diffraction of sound waves from crack tips, allowing for precise measurement of defect depth and length. This technique is especially effective for identifying critical defects such as cracks, lack of fusion, and inclusions, even in thick materials. TOFD offers fast scanning, high sensitivity, and permanent digital records, making it an ideal choice for critical weld inspections in industries like oil & gas, petrochemical, and structural steel. Our certified inspectors perform TOFD in compliance with industry standards to ensure maximum reliability and data accuracy.

Digital Radiography (DR)

Digital Radiography (DR) is a modern, non-destructive testing method that uses digital X-ray imaging to evaluate the internal integrity of welds. Unlike traditional film radiography, DR provides immediate results with enhanced image quality, faster processing, and easier data storage and sharing. This technique is effective for detecting internal defects such as porosity, cracks, and incomplete fusion in welded components. DR is ideal for high-volume inspections and critical applications where speed, accuracy, and traceability are essential. Our team uses advanced digital radiography systems to deliver efficient, code-compliant weld inspections with minimal disruption to operations.
