Here at Code a Weld, we provide comprehensive non destructive testing in Manchester, with detailed reports for each method. Non destructive testing examines damage to welded appliances and structures without compromising their structural integrity. This cost effective testing method is widely used in aerospace, the medical field, and the art to test and ensure the purity of carbon steel, stainless steel, alloys, apparatus and all structures and containers. We use the following NDT examination techniques:

Visual Inspection (CSWIP and PCN)

In visual inspection, we visually test the welds to detect surface breaking defects. We have a wide range of visual inspection equipment, including digital cameras, measuring rules and tapes, torches, markers, weld profile and undercut gauges, mirrors, borescopes and photometers. We also use fibre optic connectors for close visual inspections.

Ultrasonic Inspection

The Ultrasonic Inspection testing method is mainly used to check imperfections in the parent material and detect highly minute flaws within welded joints. This testing requires minimal preparation or set up time before carrying out the examination. We ensure quick turnaround times without compromising on accuracy.

Radiography (Not UKAS Accredited)

The Radiographic Testing method uses radiation (gamma rays or X-rays) to view the internal structure of a component being tested. This process is used to inspect specialised assemblies, such as pressure valves, for structural flaws and flux leakage. This is a very convenient testing method, and the data collected can be saved for later analysis.

Acoustic Emission Testing

Acoustic emission requires ultrasonic testing of materials, in which transient elastic sound waves are generated to redistribute stress in a material. This test has been successfully carried out on wood, polymers and concrete, among other materials. AE tests only provide qualitative analysis, and whenever quantitative analysis is required, different NDT methods can be applied.

Eddy Current Testing

Eddy Current Testing tools run by magnetism to test thin metal appliances, especially in aerospace and other manufacturing industries, to check for structural flaws or quality related problems. They can be used to measure the thickness of various metals. In some cases, eddy current and ultrasonic testing are used simultaneously.
