Design of Open Loop Control System for Cask Lid Welding Automation

The control system design of an industrial welding robot is presented. Its purpose is to automate the sealing process of a metallic cask which welds the lid of the cask on to the body. The actuation and control of the welding machine deals with the components, circuitry, and coding behind it. The components are decided based on the functional requirements, also making it safe in case of failure using Limit Switches. Two Arduino MEGA 2560 boards have been used; one to control the motion, and one to measure electrical parameters. Coding is done on Arduino IDE and the program has been tested by simulating it in WOKWI, an online Arduino simulator. A Graphical User Interface (GUI) was made using the Windows Form App (.NET Framework) of Visual Studios using C# language. The algorithm and the program have been validated using a physical mock-up.
