Multi-Layer Multi-Pass Welding Method and Apparatus, and Processor and Welding System

A multi-layer multi-pass welding method, comprising:

• a first determination step:
• before welding an ith weld layer of a weld seam, according to a first weld seam image, determining a first welding strategy for the ith weld layer and controlling a display device to display a number of weld passes of a weld layer in the first welding strategy, wherein the first weld seam image is a weld seam image after an (i−1)th weld layer is welded, and the first welding strategy further comprises a welding path of the weld pass and welding operation parameters, with i≥2 and i being an integer;
• a first control step:
• according to the first welding strategy, controlling a welding device to weld at least one weld pass of the ith weld layer;
• a first adjustment step:
• according to a second weld seam image, adjusting the first welding strategy corresponding to a current weld pass of the ith weld layer, so as to obtain a second welding strategy, wherein the current weld pass is a weld pass to be welded, and the second weld seam image is a weld seam image after a previous weld pass of the current weld pass is welded;
• and
• a second control step:
• according to the second welding strategy, controlling the welding device to weld the current weld pass.
