The present application relates to the technical field of welding equipment and welding process, and discloses a flange web plate welding system and a welding method, which comprises a support displacement mechanism, a first welding robot and a second welding robot fixedly arranged on the outer sides of the two ends of a tower pole respectively, a web plate automatic positioning device, a visual measurement system and a control system. The control system performs a three-stage welding process: in the first welding stage, all the web plates are completed in a batch symmetrical manner; in the second welding stage, intermittent annular welds are completed; in the third welding stage, before welding continuous annular welds, the root gap distribution is scanned by a weld tracking sensor, and a variable parameter welding strategy is dynamically generated according to the gap distribution to realize variable gap adaptive welding. The present application solves the problem of difficult manual positioning of the web plate, realizes full-circle welding in a half-circle working space, effectively controls welding deformation, and significantly improves welding quality and production efficiency.
