Edevis celebrates its 20th anniversary

Far-reaching commitment to nondestructive testing – enhanced defect visualization at its best.

Edevis GmbH is a spin-off of the University of Stuttgart, the result of a collaboration between Alexander Dillenz and Thomas Zweschper at the Institute of Plastics Technology, which researches and develops new methods for the nondestructive testing of materials. At the beginning of the 2000s, active thermography was brought to market maturity there.

The Motorsport department of the Porsche Development Centre in Weissach approached the University in 2002 and was looking for an innovative method for the non-destructive characterization of its CFRP monocoques (passenger cells of the Carrera GT). Thomas Zweschper and Alexander Dillenz accepted this challenge and, as part of the University of Stuttgart's technology transfer initiative, founded Edevis GmbH. To this day, Edevis maintains a close partnership with Porsche.

The successful collaboration with Porsche was followed by projects with the German Aerospace Center (DLR) and Eurocopter (now Airbus Helicopters). For the light metal foundry of BMW in Landshut, Edevis realized the first fully automated system for the series inspection of composite crankcases based on ultrasound and pulse excited thermography. This was followed by numerous other automation projects in the automotive industry.

Another milestone in the company's history is the cooperation with Thyssen-Krupp Automation Engineering. Together, the two companies developed an innovative system for the fully automated inspection of laser weld seams of cell connectors on traction batteries. This new application of active thermography has considerable future potential, particularly in the technology transformation towards electromobility.

The range of services offered by Edevis today covers the entire spectrum from flexible laboratory systems to fully automated testing systems, customer-specific software solutions and certified service testing in the field of active thermography.
