The optimal choice for weld inspection on ferrous surfaces

Track welds circumferentially or longitudinally with up to 6 probes. Follow welds with the steerable, remote-operated NAVIC - Weld Scanner, equipped with magnetic wheels, allowing vertical and inverted weld inspection to be performed easily. 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 for weld inspection.

Features

Motorized Driving and Steering

Variable drive speed and steering give the user precise control during weld inspection.

Rugged

Designed to handle intense tasks and challenging environments (dust-tight, watertight)

Magnetic Wheels

Magnetic wheels provide the foundation for scan operations on ferrous surfaces.

Low Profile Design

The NAVIC can circumnavigate pipes as small as 7 cm (2.75 in) OD while only requiring 7 cm (2.75 in) of radial clearance when low-profile scanning is needed.

Remote Control

The intuitive handheld remote control allows you to program drive paths from up to 30 m (100 ft) away. The ergonomic handheld controller includes drive paths and system diagnostics.

Battery Power

Order the NAVIC with the battery kit and avoid using heavy, cumbersome generators. These rechargeable batteries can power the NAVIC system and accessories for hours.

Many Accessories

Enhance the NAVIC's capability with optional accessories: battery-powered optical guide, onboard camera, backpack, cable management, preamp and motorized couplant pump.

Warranty

Products are engineered and designed to perform flawlessly. Our products feature a limited warranty for three years.
