Motorised Weld Scanner

SAW Bug is a motorised, magnetic-wheeled buggy that can carry up to six ultrasonic TOFD and/or phased array transducers. It is designed for the single axis inspection of circumferential welds on carbon steel pipelines from 4”OD up to flat.

With a four-wheel drive system, the magnetic buggy has excellent grip and drive power and delivers constant speed whether ascending or descending the inspection surface.

The standard SAW Bug holds four transducers: typically two phased array and two TOFD probes but can accommodate up to six probes. Its compact design makes it adaptable for the inspection of a wide range of welds from 4” OD pipes up to large vessels.

The single axis motor is controlled via a simple remote handset offering forward and reverse drive options and variable speed control for the non-steerable magnetic wheels. The motor power unit includes an emergency stop for safety and outputs the live motor encoder signals directly for connection to any industry standard instrumentation.

A corrosion mapping arm is also available, as an optional extra, for SAW Bug to carry out C-scan inspections.
