Falcon – Steerable Magnetic Scanner
The Falcon is a powerful, magnetically attached 4×4 wheel drive scanner designed for single-axis weld inspection with conventional UT (TOFD/pulse-echo) and phased array (PAUT) or eddy current array (ECA) probes. The remote control feature allows operators to inspect hard-to-reach or hazardous areas, increasing safety and efficiency.
The Falcon comprises two mutually articulated magnetic wheeled modules, each powered by a high-torque DC servo motor. A chain-driven, four-wheel drive system allows the scanner to traverse surfaces, overcoming obstacles such as weld caps. An articulated joint between the modules provides two degrees of freedom, helping all four wheels maintain contact on curved surfaces, as the scanner is steered or rotated.
A closed-loop servo system provides velocity control of the two motors ensuring smooth operation of the Falcon. This feedback control ensures the output speed of the scanner remains constant, regardless of orientation or drive direction.
Operation of the Falcon through the remote control uses thumbwheel joysticks providing skid steer motion. The analogue thumbwheels allow for fine adjustments of each motors’ speed for precise steering.
The Falcon parts have been designed to minimise setup times and the probe mounting frame, which connects to one of the drive modules, supports up to six ultrasonic transducers and a positional encoder.
Unless limited by physical obstruction or cabling, the Falcon is capable of a full 360° circumferential weld scan of a pipe or vessel and the umbilical cable length can be customised to your inspection requirement.
The Falcon is a precision automated inspection solution supporting productivity and accuracy while reducing risk and inspection time.
