This work consists on a statistical study of an industrial welding process that consist on a forming and welding pipes plant from coils and plates. In it, we will study the influence of oscillations on three parameters that we consider the most important Welding Voltage (V), Welding Current (A) and Stickout Speed (mm / sec). We will use statistical analysis to find the optimization equation of the system through software such as Minitab, as well as the lower and upper control limits, Average of the parameters in the process, the variance and the standard deviation of the parameters, to understand how to improve the industrial process, minimizing problems and focusing on critical parameters. With the results obtained we will present them to the studied plant, verifying the possibility of using the optimization equation obtained in the graduation work, thus confirming that the path taken for the improvement of the theoretical process is also applied in practice, being able to reduce cost and process time. We hope to conclude with the project the best working conditions we can use so that the variations are controlled in a way that minimizes them
