The invention belongs to the technical field of welding metal materials, and relates to a method and system for judging welding defects by measuring welding temperature. According to the method for judging the welding defects, the computer runs an executable program of the pipeline welding defect recognition model; in the welding process, welding current, welding voltage, the movement speed and the wire feeding speed of a welding gun and temperature data obtained by a temperature measuring device are collected; the temperature data are imported into an executable program of the pipeline welding defect recognition model, and the executable program of the pipeline welding defect recognition model judges whether defects exist or not. The system for judging the welding defects comprises a sliding assembly, a welding device and a welding defect detection device, the welding device comprises a welding machine and a welding gun, and the welding defect detection device comprises a temperature measuring device and a c
