    Abstract: A welding quality detection system and a welding quality detection method are provided. A detection device applies a force to at least one weld point of a first welded object or a second welded object that are welded together. A displacement detector detects a displacement signal that varies with the force or time between the first welded object and the second welded object based on the force. A detection module receives or records the displacement signal and determines whether a gap exists between the first welded object and the second welded object based on a slope of the displacement signal, so as to detect the welding quality of the weld point quickly and precisely.
