The purpose of this work was to analyse the quality of the product made by hand with spot welders and to analyse the quality of the product made by the industrial robot "Fanuc Robotics S-420i". The product was a front panel of the car body, made of semi-finished products in the process of spot welding. In conclusion, it was stated what is the impact of production automation on the quality of the product. Applications of robot welding process are used not only because of better quality parameters, but also due to significant reduction of production costs and less fatigue of employees. The robot operator is a quality controller and contributes to quality management.
