NAVIC – Weld Scanner

The optimal choice for weld inspection on ferrous surfaces

Track welds circumferentially or longitudinally with up to 6 probes. Follow welds with the NAVIC – Weld Scanner which operates remotely with magnetic wheels which allow vertical and inverted weld inspection to be performed with ease. Various probe holder frames expand the weld scanning possibilities. From low-profile for restricted access to spiral welds and long seam inspection, the NAVIC is the industry leader in non-destructive testing.

Component Identification

The powerful base crawler carries probe holder frames, raster arms and a multitude of accessories for the purposes of weld and corrosion inspection.

A spring-loaded encoder maintains surface contact on all various scan surface diameters.

Powerful magnetic wheels ensure the crawler remains fixed to any ferrous surface.

Compatible with both North American and European power sources, the power controller connects the user instrument and handheld controller to the base crawler.

The backbone of communication between the power controller and the base crawler.

Containing the NAVIC operating system, the handheld controller joysticks control speed and steering of the base crawler while the intuitive touchscreen allows for more intricate raster path and drive programming.
