Non-destructive testing is used to examine damage on welded appliances and structures without compromising their structural integrity. This cost-effective method maintains the durability of appliances.
At Code A Weld, we specialise in all NDT procedures across the UK. Our NDT examination techniques are backed up by the latest non-destructive testing equipment for high-tech services, including Eddy Current testing appliances. Our professional welders work precisely to customer specifications and test raw materials and components.
Our Non-Destructive Testing (NDT) services include:
Visual Inspection (CSWIP and PCN)
Visual inspection involves visual testing of welds and can detect surface-breaking defects. Our visual inspection equipment and consumables enable us to perform the test correctly. These include a digital camera, measuring rules and tapes, torch, markers, weld profile and undercut gauges, mirrors, borescopes and photometer. We use fibre optic connectors for close visual inspections.
Ultrasonic Inspection
Ultrasonic Testing (UT) or Ultrasonic Inspection (UI) is a popular method of Non-Destructive Testing. This method is most commonly used to check the thickness for laminations in the parent material and to detect highly minute flaws within welded joints.
The procedure involves inspecting the object in an ultrasonic transducer connected to a diagnostic machine. Then, a short wavelength and high frequency are transmitted through the object. These waves are then measured and compared with existing standards to verify the inspected object. Pulse waves reveal the object’s thickness and any internal imperfections.
Radiography (Not UKAS Accredited)
Radiographic Testing uses radiation (gamma rays or x-rays) to view the internal structures of a component. This process is usually used to inspect specialised assemblies, such as pressure valves, for structural flaws and flux leakage.
Compared to other testing methods, radiographic testing is more convenient as it’s highly reproducible and abundant in material, and the data can be used for further analysis.
Acoustic Emission Testing
Acoustic Emission (AE) Testing is a non-destructive testing (NDT) technique used to detect and find defects or changes in materials, typically in structures under stress or pressure. It monitors the acoustic signals the material emits when it undergoes deformation or damage.
AE testing is used in various industries, such as aerospace, civil engineering, manufacturing, and oil and gas. It can detect defects like cracks, delaminations, and corrosion in materials like metals, composites, and concrete.
Eddy Current Testing
Eddy Current Testing is generally performed on thin metal appliances, especially in aerospace and other manufacturing and service environments, to check for structural flaws or quality-related problems. This test also measures the metal thickness, such as identifying rust and corrosion under jet skin.
