Mecanum Wheeled Mobile Robot for Welding Process

Welding is a sculptural process which joins the metals by fusion process. It is a permanent metal joining process and is being used in most of the industries to join the metals. The need for the autonomous welding tasks is increasing rapidly to improve the productivity. However, the robots used for this work are at a fixed location and it is moved from one working location to another by crane. Therefore the proposed work rectifies this issue by providing the moving platform for mobility of the robot. The ultrasonic sensor is employed on the mobile platform to sense the seam to be welded and simultaneously welding profile is recorded in the controller. After sensing the seam, the robot starts welding in the sensed path. For proper sensing of the seam, the groove has been provided on the workpiece. This robot is designed for the Metal Inert Gas (MIG) welding; however, it can be used for Gas welding, Arc welding and Tungsten Inert Gas (TIG) welding with little modifications
