Non destructive testing for Automotive

Non-destructive tests for automotive: TEC Eurolab solutions 
Interview with Mr. Stefano Benuzzi - Managing Technician Inspections and NdT



For non-destructive tests in the Automotive industry TEC Eurolab offers an integrated approach using standard and advanced methods. Could you describe this “modus operandi”?
Amongst the different sectors of the manufacturing industry, automotive has been one of those in which, along the years, technological innovations have changed the methods for components’ manufacturing and construction. Likewise, the change in manufacturing technologies has required an ongoing innovation and renewal of the testing methods. For the analysis of components in this sector, TEC Eurolab offers a service procedure of non-destructive testing that resorts to both innovative and well-know, consolidated methods. When a new component is manufactured, TEC Eurolab will scan it through an industrial CT scan thereby obtaining complete information as to the presence of possible internal flaws; then, once the component has entered production, the testing methods must be as reproducible as possible on a large scale: this is when consolidated non-destructive tests that can spot possible flaws during the manufacturing stage on the basis of the results achieved by tests on prototypes, come into play.

What are the non-destructive testing solutions in the field of composite materials that you deem more effective?
A good example of a surface analysis is that with penetrating liquids or a simple visual examination that can often detect possible problems quickly and with a good margin of reliability. For volumetric tests, given the manufacturing mode and the most defects types, ultrasonic testing is the most reliable method since it can detect indications of delamination, voids and/or lack of gluing resin.

TEC Eurolab has grown significantly in the past years. What are the expected innovations for 2019?
For the testing of composite materials, we are working at a prototypal characterization through CT scan followed by ultrasonic production tests. Regarding the latter, immersion and water column UT tests are implemented which offer the possibility of recording the scan with C-Scan mode. Great attention is also paid to the evaluation of semi-automatic thermography systems that can replace more classical tests such as penetrating liquids when searching for surface and sub-surface flaws.
