Draisine WPG D340

Eddy current testing instrument for track inspection for global use The Rohmann trolley is suitable for different track gauges  
The WPG D340 trolley brings eddy current onto the rail, so they say at Rohmann GmbH, based in Frankenthal, Germany. The specialist in non-destructive testing now supplies this successful product all over the world. While the trolley has so far been manufactured individually for different track gauges, Rohmann GmbH now offers an adjustable version in addition, for a more universal use with track gauges from 1,400 to 1,700 mm. This may not only please the railway companies, but also their service partners who maintain the tracks. A trolley that has been manufactured for the German track system can now also be used for the inspection of rails abroad, which of course saves costs.

New Eddy Current Test Instruments for the Training Center of the German Society for Non Destructive Testing (DGZfP) in Magdeburg
For years Rohmann GmbH has been working closely with training institutions. This has ranged from common research projects with universities in the field of non-destructive testing by eddy current up to visits from apprentices and university students at our headquarters in Frankenthal. It is important for us to demonstrate the diversity of testing tasks and solutions with eddy current using practical examples and to arouse interest in non-destructive testing. On February 19, 2020, together with Thomas Schwabe and Jürgen Lauer, Petra Rohmann, managing director of Rohmann GmbH, visited the Training Center of the DGZfP in Magdeburg. She brought two new ELOTEST PL600 eddy current testing instruments with her. Petra Rohmann appreciates the work of the DGZfP and was happy to support the training center by loaning two inline testing instruments to them. Holger Nowak, DGZfP head of the department for eddy current testing in Magdeburg, accepted the instruments with thanks. The visit was concluded by a short briefing on the use of the instruments.

Mobile rail processing using rotary planer on railway tracks and at switches
However, efficiency in switch processing also results from joint preliminary acceptance of the switches by the customer and contractor. This includes determining the geometric conditions and checking the material-side damage to the switch, determining the processing lengths A, B and C after the beginning and end of the switch, deriving the construction requirements and determining the processing time separately for main and side track. Proof of the HC-free condition of machined rails Similar to the grinding and milling machines and the planer, the D-HOB 2500 is also currently equipped with eddy current testing technology. The test system developed by the companies Rohmann GmbH, Frankenthal and Mevert Maschinenbau GmbH, Lauenhagen with the cooperation of Schweerbau consists of - one sensor carrier per rail, - two test sensors per sensor carrier, - an industrial eddy current tester type Elotest PL500, - a data server PC, - a terminal PC with visualization software and printer. The sensor carriers can be lowered and raised during the machining process. They position themselves automatically, are guided along the running edge and are suitable for soft ground. The inspection is carried out in the tracks 9.2 mm and 17.9 mm from the running edge. The maximum test speed is 20 km/h. The testing devices are calibrated on workdays according to customer specifications.

Non-destructive testing with eddy current – parts and components of turbochargers
Parts and components of turbochargers are exposed to the highest loads during operation. The turbocharged engines used today are dependent on the operation of high-precision and reliable turbocharging technology at low displacement and high speeds.  A component that is subject to particularly high stress is the so-called compressor wheel (Fig. 1, red frame). One of the most highly stressed zones of these compressor wheels is in the area of the central bore, which connects the wheel with the shaft of the turbocharger (Fig. 2; red frame). After a damage case in which a breakage of the wheel in this critical area led to the failure of the turbocharger, a test procedure using eddy current technology was developed in cooperation with Rohmann GmbH. The publication of the article was made possible by close cooperation with Mrs. Dipl.-Ing. Angela Au (Head of Materials Engineering; PRÄWEST) and Mr. Dipl.-Wi. Stephan Reich (Head of Quality Assurance; PRAE-TURBO GmbH & Co.KG)

Rail inspection at speed 200 km/h
Frankenthal-based Rohmann GmbH plans to market a new analysis technology worldwide and has identified a large market for this technology. The company's CEO Jürgen Rohmann announced that the company will initially equip a test train of the Bahn AG with the new so-called scor technology. The company will then market the method worldwide. The durability of tracks is estimated at 30 to 50 years; the demand for reliable testing technology is high. "Non-destructive materials testing" is what Rohmann's equipment makes possible. Eddy current testing technology can be used to examine all electrically conductive and at the same time magnetized materials. For this purpose, the test object is exposed to the effect of an electromagnetic alternating field.
