The Radian Robotics Inner-Diameter Welder is a sustainable and cost-effective system designed to spot-weld in the eye of a coil so that the inner flap is fixed and does not fall back. An additional option is to spot-weld over the whole diameter of the eye so that a sleeve is redundant.
The Inner-Diameter Welder works on a standard robot for optimum mechanical reliability. The robots we use are operational in many steel plants and are specially designed to work under extreme conditions.
The robot has a specially designed head where the inner coil diameter and the head of the plate are measured by a laser. Also located in this head are the welding electrodes. After the measurement, the robot head will spot-weld the plate in several places.
