Surface condition is critically important for the effectiveness of various NDT (Non-destructive Testing)techniques, such as UT (Ultrasonic Testing), PAUT (Phased Array Ultrasonic Testing), TOFD (Time-of-flight Diffraction), MT (Magnetic Particle Testing), PT (Penetrant Testing). The robot is designed to prepare the inspection surface on ferromagnetic plate, pipe, vessel and tank, etc., so that NDT techniques can be successfully applied.Programmable control and automatic precise grinding significantly improve productivity!
1 Product Features
No scaffolding needed. Equipped with four high-strength magnetic wheels, the robot can climb up 20meters (66 feet) above the ground.Integrated video camera, it can monitor and adjust the detection position and route of high-altitude components in real time on the ground to ensure the controllability of scanning track.
Adaptive grinding to convex and convex surfaces thanks to cylinder thrust. Precisewheel maneuvering(left-right swing angle from 0°-20°, forward- backward angle 0°-39°, vertical displacement 30mm)guaranteesthe surface grindingconsistency,which is critical for success of UT, PAUT, TOFD, MT and PT methods.
Programmable control of grinding operation through the integrated display screen on handhold controller. Automatic precise grinding allows one operator to run multiple robots on large surfaces, significantly improve productivity.
Four-wheel drive mode powered by 4 sturdy motors. Independent suspension design allows the robot todrive smoothly through uneven barrier, such as weld cap.
Safe grinding operation on horizontal, inclined, vertical and upside-down positions.
Adaptable to a variety of 4-inch grinding wheel, such as flap wheel, wire wheelbrush, etc.
