MIG WELDING SYSTEM

摘要

The present invention relates to a MIG welding system comprising the steps of: operating a vision module and a welding device; capturing a thermal image of a welding part through an infrared thermal camera connected to the vision module, and converting the image to an image signal and transmitting same to the vision module; detecting whether there is slag through the vision module; when slag is detected through the vision module, determining whether the detected slag is fixed; and when it is determined that the detected slag is fixed, analyzing the position of the slag and calculating coordinate values. Even when a worker does not confirm fixed slag with the naked eye, the position of the fixed slag that has not been confirmed with the naked eye can be confirmed through the calculated coordinate values.
