Abstract: An automated multi-pass welding method is provided. An optical measuring instrument measures a welding space to obtain reference geometry information, and then the reference geometry information is inputted into an AI model to obtain control parameters that are used by a welding device and a robotic arm as operation settings to perform welding. The optical measuring instrument measures the welding space after the welding to obtain post-welding geometry information for a computerized control device to generate a classification result. When the computerized control device determines to form a next weld pass based on the classification result, the aforesaid actions are repeated until the computerized control device determines to stop welding.
