Modular Rohmann concept for the non- destructive testing of pipes and rods

Defect inspection on rotating tubes using eddy current and ultrasonic

New Compact Weldac A small revolution Sometimes, big things come in small packages, or, as in the case of the new Compact Weldac, in a small cabinet. Less than 1300 mm tall, this high-output solid-state welder uses minimal space while yielding a lot of power. • The most power in a small cabinet • Output power upto 300 kW in a single cabinet • Small footprint, fast installation, easy to retrofit • High-efficiency SiC inverters • 91% efficiency from mains to the welding coil • Unmatched uptime and efficiency • Can be set up for Industry 4.0 factory network

GERMAN company Rohmann offers a modular concept for materials testing with eddy currents with its ELOTEST PL600, a digital eddy current test instrument. The company has been developing and marketing eddy current testing instruments and accessories for non-destructive materials testing for more than 43 years and has now released a single device that can display the results for different testing techniques such as rotors, coaxial coils or yokes for magnetising and demagnetising the test piece used in the production line. Whether crack detection or material mix-up, ELOTEST PL600 displays the test results of different testing stations, which in the past required several devices along the line. The modular concept for testing long products together with the licensing system for the ELOTEST PL600 allow for a short change-over time, a straightforward exchange of the testing techniques and an upgrade of the eddy current testing instrument, which is possible at any time. ELOTEST PL600 has been supplemented by a 19” (PL600/R) and a compacter 9.5” (PL600/RC) remote version for integration into automated systems. The EloLine software, which is used during the testing of long products, has also been developed by Rohmann and serves to visualise and record the acquired results. Serial part numbers, batches, serial numbers, length of the tested parts and the name of the inspector can be saved in the database and a detailed test report for every tested part or a report on a specific production batch can be produced.

The sustainable choice EFD Induction’s new Compact Weldac lifts the climate action of the tube and pipe industry to new heights. Its high efficiency saves energy and reduces cooling water consumption.
