ROWA-B – Bar Tester

GE’s ROWA-B is a compact phased array ultrasonic testing machine for round/square/hexagonal bars and is designed for direct integration into the production line. The test functionality comprises the detection of core defects and (sub-) surface flaws. The ROWA-B has no mechanically moving parts, which guarantees short changeovers, low wear, easy maintenance and therefore low operating expenses. Different models are available for bar diameters from 7 mm up to 250 mm.
