Description

KALMAR 32+ RWE is a stationary phased array flaw detector designed for acceptance ultrasonic inspection of electric contact welded rail joints at rail welding enterprises. It is a mechanical scanner with pre-installed phased array transducers, a flaw detection unit and a PC control tablet. The scanner is installed in the center of the weld joint; using a mechanized drive, transducers move along the generatrix of the weld across the entire rail cross-section — head, web, and base blades.

In real time, a B-scan is displayed on the flaw detector screen as a rail contour with defect parameters: coordinates, location in the weld section, conventional dimensions, and detectability coefficient. Detailed analysis of all signals is available in A and S scans. The flaw detector software includes standard settings for aluminothermic, electric contact and gas press welding per current regulations. Inspection results are saved in a database with full diagnostic parameters including sensitivity, test time, defect sizes, detection rate and GPS coordinates.
