Exhibits of the 19th Special Show »Non-Contact Measurement Technology«

The Special Show »Non-Contact Measurement Technology« at the international trade fair for quality assurance »Control« in Stuttgart, May 6th to 9th, 2025, will be held for the 19th time this year and will present the latest developments and pioneering technologies from the field of non-contact measuring and testing technology. The Special Show has established itself as a marketplace of innovations for both exhibitors and trade fair visitors and will be on display at booth 7401 in a centrally located position in hall 7 this year.

The Special Show, whose concept it is to present a variety of different technologies for non-contact and non-destructive measuring and testing technology in a concentrated area, offers interested parties and potential users initial guidance when selecting a suitable technology in order to master their own testing tasks. This is because the performance and flexibility of modern systems is constantly growing. Wider and wider scales are being covered and new fields of application explored. Due to the rapid pace of technical development, it is not easy for users to orient themselves on the market and make a suitable selection with regard to their own requirements.

In addition to this initial orientation aid, the exhibitors at the Special Show booth also offer complete non-contact measuring and testing systems, where visitors with specific tasks can find possible solutions.

The Special Show is being organized with the support of the Fraunhofer Business Unit Vision and P. E. Schall GmbH & Co. KG.

Test head for detecting defects in weld seams using laser thermography

edevis GmbH from Leinfelden-Echterdingen is presenting a laser testing head for detecting defects in weld seams made of various materials (e.g. aluminum, steel or copper) and cell connectors up to 1 mm. The system is based on the principle of heat flow thermography. A laser is used to briefly heat a test sample in a non-destructive manner. Phase images make the heat flow in the test area visible and provide information about structural changes that may be hidden beneath the surface. This is because the correlation between heating and cooling makes it possible to determine whether a cell connection is defective.

Practice-oriented knowledge on the use of industrial image processing

Image processing and non-contact measurement technology are used successfully today across all stages of the industrial value chain. Innovative technologies are an important element in the implementation of zero-defect concepts, aiming for 100% inspection in production, and support the development and qualification of new products. However, it is still not easy for potential users to decide which image processing technology is most suitable for their own applications. The on-site practical seminars, video seminars, technology days and publications from the Fraunhofer Business Unit Vision offer a decision-making aid for this.
