Pipe system delivers sports car sound Norma Group has developed, on behalf of a sports car manufacturer, a pipe system designed to transmit engine sounds. Drivers of an upgraded edition of a sports car due to be launched on the German market in the spring will actually be able to hear the high engine power, even though modern technology and insulation typically shield passengers from engine noises. The sound tube will meet a sports car driver’s desire to listen to the engine working. The specifically designed Normafluid sound system is an acoustic application that amplifies the sounds of an eight- cylinder engine via a ‘Sound Symposer’. Plastic tubes serve as acoustic channels of the exhaust system transmitting the sound from the engine into the cabin. These pipe systems contain membranes and controllable valves that can be activated or deactivated to experience the engine sound by the push of a button.

Expertise in Flow Technologies

Norma Group AG – Germany info@normagroup.com www.normagroup.com Seam quality evaluation

Flow technology is becoming an increasingly important issue – all over the world. Technological innovations have reached high standards and are beginning to open up horizons. They will be on display in Düsseldorf, Germany and at the international events organized by Messe Düsseldorf and its partners. The undisputed No. 1 trade fair for the tube industry is Tube in Düsseldorf, Germany. Every two years it presents forward-looking solutions which the top decision-makers expect. But, even in the interim period, Messe Düsseldorf offers opportu- nities to keep in touch with the market. Whether autonomously or in cooperation with various organizations, Messe Düsseldorf pro- motes professional events within strategically important growth markets. Whether in Düsseldorf or trade fairs held in Arabia, China, India or Russia, exhibitors and visitors alike can rely on the competence and experience of Messe Düsseldorf . www.messe-duesseldorf.de

HKS-Prozesstechnik GmbH specialises in the area of welding monitoring and measuring systems. Tubes that seem to be completely physically correct can fracture in use. The reason for this, especially in ERW welding processes, is too low or too high heat input or material faults. The evaluation of seam quality by using its thermal field opens up new possibilities. Even penetration faults or seam asymmetry can be recognised in the running production, and every inch of the tube is controlled and documented. The ThermoProfileScanner (TPS) from HKS-Prozesstechnik makes this possible. Operation next to the welding spot is possible through a glassless, gas purged and water cooled construction. From the recorded thermal data the welded seam’s basic parameters are calculated. The threshold is freely adjustable and therefore adaptable to the respective process. The basic parameters like seam position, width, symmetry and temperature are the base to recognise such weld defects as lack of fusion, cold welds, pores or seam offset. For weld inspection purposes, the characteristic of the heat- affected zone (HAZ) depends directly on the weld seam quality. Therefore unacceptable seam irregularities and weld defects will be detected, marked and sorted out.
