Welding Engineering Inspection Services
Bespoke Fabrications can offer Welding Inspection and Non-Destructive Weld Testing to suit our client’s specific requirements. Non-Destructive Testing covers a broad group of techniques used to evaluate the properties of a material, part, product, or weld without materially affecting the integrity of the piece being inspected or investigated under the test procedure.
This is a method of non-destructive testing used to assess the quality of welds in accordance with BS EN 5817 / ASME standards. Visual inspection is an inexpensive method of evaluating the condition of weld joints, however it requires a high degree of skill and experience to critically detect any flaws and/or surface breaks in the weld, often requiring good lighting and specialist cameras, mirrors, and borescopes.
Magnetic Particle Inspection is the process for detection of surface, and slightly sub-surface cessation using finely divided ferromagnetic particles to indicate defects in magnetic materials. Ferromagnetic particles are applied to the test surface, and magnetic yokes are used to generate a magnetic field to pass through and around the test surface. These particles register abrupt changes in resistance in the path of the magnetic field and will therefore be attracted to; and outline the crack or anomaly if there is one.
Dye Penetrant Inspection can also be known as liquid penetrant inspection or penetrant testing and is used to locate surface cracks and defects, and the porosity of the material. It is easy to perform and easy to clean up, causing minimal disruption to productivity, but also only detects flaws on the surface of the material. Dye Penetrant Inspection (DPI) is a portable and efficient method, meaning testing can be conducted at our manufacturing facility, or on-site at our client’s request. It can be used across a variety of materials to quickly observe large and difficult surface areas.
Ultrasonic Testing is one of the most accurate Non-Destructive Testing (NDT) methods, to detect subsurface flaws deep within the test piece, for material thicknesses from 8 mm thick up to as thick as commercially available, and is highly sensitive, enabling extremely small flaws to be detected. Ultrasonic Testing (UT) uses electronically produced high-frequency sound waves to penetrate metals such as steel and other alloys, with short ultrasonic pulses passing through the metal. As there are no chemicals used, this method is non-hazardous so will not affect others nearby, and the results immediate.
Ensuring absolute confidence by taking critical components to the extreme, hydrostatic testing is an essential part of critical component analysis, used for checking components under pre-determined conditions to minimise the risk of fatigue failure once commissioned.
The non-destructive testing methods we offer are designed to comply with a variety of industry standards with our inspectors qualified to CSWIP or PCN, and our weld tests can be 3rd party UKAS approved on request. We work to all BS EN, AWS, ASME, NORSOK, BS 4872 qualifications. We serve many sectors and can test raw materials such as sheet, plate, bar, and pipe through to stand-alone components.
