Robots are commonly used for spot welding automobile bodies because the task is repetitive and often hazardous or uncomfortable for human workers. By performing these operations, robots serve as a substitute for human labor in environments that require consistent, high-volume output.1

In the automotive industry, robots are programmed to position a spot welder against vehicle panels and frames to assemble the basic car body. This application is highly effective because robots can execute the same basic motions every cycle with precision, helping manufacturers maintain the efficiency of the assembly line. Furthermore, the use of automated equipment like robots allows companies to manage high-volume production while mitigating the high costs associated with manual labor.123
