Intelligent automated multi-pass welding method

An automated multi-pass welding method, comprising steps of:

• A) by an optical measuring instrument, measuring a welding space formed by two steel components that is in contact with each other, thereby obtaining reference geometry information of the welding space;
• B) by a computerized control device, inputting the reference geometry information of the welding space into a first artificial intelligence (AI) model, thereby obtaining control parameters of a welding device and a robotic arm, where the welding device is to be used for welding, and the robotic arm is used to operate the welding device;
• C) by the welding device and the robotic arm, using the control parameters as operation settings thereof to cause the welding device to work with a welding wire feeder to perform welding on the welding space, thereby forming a weld pass in the welding space;
• D) by the optical measuring instrument, measuring the welding space after the weld pass is formed in the welding space, thereby obtaining a post-welding geometry information of the welding space;
• E) by the computerized control device, generating a classification result based on the post-welding geometry information of the welding space;
• and
• F) by the computerized control device, upon determining, based on the classification result, to form a next weld pass in the welding space, repeating steps B) to F) with the post-welding geometry information of the welding space serving as the reference geometry information of the welding space, until the computerized control device determines to stop welding based on the classification result.
