DESCRIPTION
Marposs NDT electronics E70S and E59N are based on the working principle of eddy current this technique generates onto the specimen under test, the so called “eddy current”; that are small loops of electric current induced by a time varying magnetic field.
The presence of superficial defects or differences on the material composition, will change the normal behavior of the eddy current. These changes are detected by eddy current electronics E70S and E59N to sort good from bad parts.
A magnetic field is generated by an eddy current probe, properly designed to fit applicative problems. The strength of the magnetic field is enough to detect superficial defects, or material deviations with no risk of leaving residual magnetization on the part tested; so that it can complete its production process.
E70S and E59N electronics can be used as part of Marposs’ turnkey applications, or as components to be integrated into customer applications.
In case of doubtful applicative problems, Marposs can examine the feasibility of the check by making tests on parts supplied by the customer, suggesting the proper combination of sensors and electronics.
BENEFITS
Machining processes such as turning, grinding, drilling, thermal treatments, or casting may generate defects that need to be detected in order to avoid the breakdown of mechanical components; if undetected these components could compromise the users’ safety. Quality assurance of every part produced, proves that having reliable technology to inspect 100% of produced parts, at typical production line rates, is crucial.
Non-destructive tests (NDT) based on eddy current, allow testing the properties of the materials without the need of part preparation such as deep cleaning or degreasing. E70S and E59N, in combination with properly designed eddy current sensors, provide a shop floor solution for automatic inspection systems of mass production components to check:
- material integrity to detect superficial defects such as cracks, porosity, blow holes, etc.;
- material properties to verify superficial hardness and case depth;
- material identification to avoid material mix of part having same geometry but made with different materials.
Thanks to the following advantages of eddy current technology:
part preparation is not need
there is no contact between eddy current probe and inspected part
possibilities to use both fixed and scanning probes
A test speed higher than any other NDT techniques is possible, which makes it useful for carrying out the checks automatically on 100% of the production, as a final inspection.
From the simplest screw to the most complex crankshaft, with tailor made automatic solutions and more than 350 eddy current probes in portfolio, every specific inspection problem can be solved.
