PD Engineering Inspection Services is conducting Radiographic Testing (RT) using both Gamma rays and X rays to inspect the internal structure of materials. Gamma ray radiography, utilizing radioactive isotopes like Iridium-192, is ideal for inspecting thick and dense materials such as metal welds and castings, offering deep penetration and portability without the need for external power.
In contrast, X-ray radiography, generated by an X-ray tube, provides high-resolution images suitable for thinner materials and precise inspections, making it ideal for components like electronics, aerospace parts, and composite materials.

PD Engineering Inspection Services also offers Ultrasonic Testing (UT), a highly effective non-destructive testing method that utilizes high-frequency sound waves to inspect the internal structure of materials. UT is particularly valuable for detecting internal flaws such as cracks, voids, and inclusions in metals, composites, and plastics.
The process involves transmitting ultrasonic waves into the material and analyzing the reflected signals to identify any discontinuities or measure thickness. This technique is versatile, providing immediate results and the ability to inspect complex shapes and sizes. Additionally, UT is portable and does not require radiation, making it a safer option for operators.

PD Engineering Inspection Services also provides Magnetic Particle Testing (MPT), a non-destructive testing method used to detect surface and near-surface discontinuities in ferromagnetic materials. MPT involves magnetizing the material and then applying ferromagnetic particles to the surface.
These particles gather at areas where there are discontinuities, such as cracks or voids, creating a visible indication under proper lighting conditions. This method is highly effective for inspecting welds, castings, and other critical components, providing immediate and reliable results.

PD Engineering Inspection Services also offers Dye Penetrant Inspection (DPI), a widely used non-destructive testing method for detecting surface-breaking defects in non-porous materials. DPI involves applying a visible or fluorescent dye to the surface of the material, allowing it to seep into any cracks or imperfections.
After a sufficient penetration time, the excess dye is removed, and a developer is applied, which draws the dye out of the defects, making them visible under appropriate lighting conditions. This method is particularly effective for inspecting metals, ceramics, and plastics for surface cracks, porosity, and other flaws. DPI is appreciated for its simplicity, low cost, and ability to provide immediate results without the need for complex equipment.

PD Engineering Inspection Services also offers Thickness Measurement services, utilizing advanced non-destructive testing methods to accurately determine the thickness of various materials. This service is crucial for assessing the integrity and longevity of components, particularly in industries where material thickness is a critical factor, such as in pipelines, pressure vessels, and structural steel.
Techniques such as Ultrasonic Thickness Measurement involve sending high-frequency sound waves into the material and measuring the time it takes for the echoes to return, providing precise thickness readings without damaging the material.
