OTHER / ADVANCED NON-DESTRUCTIVE TESTING
Domson also performs various other types of non-destructive testing including hardness testing, magnetic flux leakage (MFL) testing, and vacuum testing.
Hardness Testing
Hardness testing is performed in the field with a small hand-held device and is used to gauge the strength of the metal. This is useful when determining the correct welding electrode to use during structural repair.
Magnetic Flux Leakage Testing
Magnetic flux leakage, or MFL testing, is used to find areas of metal loss due to corrosion or erosion. It is most common in inspection of pipelines, tank floors and heat exchanger tubes.
Vacuum Box Testing
Vacuum box testing is used to test the integrity of the seal between two plates, usually on a lap weld joint. A bubble solution is first applied to a clean, bare weld surface. The vacuum box is then placed over the joint and the compressor turned on until the gauge indicates a vacuum. Any tiny holes or cracks that penetrate through the joint will cause air to be drawn up from the opposite surface, through the solution, and will form bubbles.
Vacuum box testing is commonly used in tank inspections for roof and floor repairs. Special box shapes can be made to test corners and curved surfaces.
