The robot rotates about the pipe carrying a coil connected to an inverter-induction generator, creating heat in the wall of the pipe.
A coil is common to a range of pipe diameters and the technology is applicable from 12 Inch to very large diameter pipes, especially when coating with liquid systems.
The robot adapts to variations in the pipe circularity and eccentricity between the guidance track. Thus, ensuring a perfectly uniform heat input about the entire joint surface. Each orbit of the robot increases the heat, with the speed and energy being regulated in relation to the angular position.
The across joint temperature profile is generated to maximise the efficiency of cure across the joint, whilst keeping the required heat input to a minimum. Particularly important when applying FBE powder systems.
