What is Superficial Non-Destructive Testing
The term “Non-Destructive Testing” includes all tests and examinations aimed at locating and identifying defects in a structure or a mechanical part, without the removal, alteration or destruction of material. For this reason they are of fundamental importance in all those sectors in which all pieces coming out of production must be verified for the absence of defects or anomalies, or tested during maintenance. In fact, Non-Destructive Testing systems make allow for verification of the absence of anomalies while maintaining the integrity of the piece, thus allowing for its subsequent use.
In the specific case of Non-Destructive Surface Testing, the systems which are normally employed allow for control in the vicinity of the surface of the piece, and are therefore suitable for detecting the presence of indications and defects such as cracks.
Flux Non-Destructive Surface control systems
Delta Flux specializes in the design and construction of machines and systems for two specific types of Non-Destructive Surface checks, and for the supply of related accessories and consumables:
Machines for Non-Destructive Magnetic Particle Inspection
Machines for Non Destructive Penetrant Liquids Testing
The importance of superficial and sub-superficial controls
Checking the integrity of parts of critical importance, in all industrial sectors, is essential for the safety and good functioning of the parts produced. In fact, even the smallest superficial crack, as well as any other defect, will always tend to grow under the action of stresses, leading to component failure. The use of systems for Non-Destructive Surface Tests, which sometimes may even include the detection of sub-surface defects, is therefore essential in quality control procedures, to allow the supply of pieces which may be guaranteed to be free from critical defects.
The fields of application of Non-Destructive Testing
There are many industrial and engineering fields in which it is necessary to accurately control all manufactured pieces through the use of systems for non-destructive surface tests. A partial list includes:
Fields of application
- Aerospace sector
- Automotive sector
- Railway sector
- Nuclear industry
- Energy sector
- Naval industry
- War industry
- Oil & Gas and oil industry
- General Industries
- Production of earth moving systems
- Hot stamping
- Thermal treatments
