Name: ED-W10mm – Eddy Current Flaw Detector
Brand: NDT1 KRAFT

Description

The ED-W10mm is a specialized eddy current flaw detector for detection and depth measurement of surface-breaking defects in welds and other areas with strongly non-uniform electromagnetic properties. Typical inspection zones include the weld metal, near-weld area and heat-affected zone.

The 10 mm sensing system is designed in accordance with the inspection concept referenced by ISO 17643 and provides defect depth measurement from 0.5 to 10 mm. It can be used on coated and uncoated welded components and is specifically intended for conditions where variations in material structure and electromagnetic properties make conventional surface-crack inspection more difficult.

Unlike the ED-1mm, ED-3mm and ED-6mm models, which are selected primarily according to defect size, depth and surface roughness, the ED-W10mm is selected primarily according to the inspection object: welded joints and their heat-affected regions.
