Abstract: A welding quality detection system and an ultrasonic welding device, and a welding quality detection method are disclosed. The welding quality detection system includes a detection module, a control module and a display module. The detection module is configured for collecting a transverse friction force and a longitudinal welding pressure of a welded workpiece. The control module is electrically connected with the detection module, and the control module is configured for receiving, analyzing and processing a transverse friction force signal and a longitudinal welding pressure signal of the detection module. The display module is electrically connected with the control module, and the display module is configured for displaying analysis results of the control module. According to the application, a welding quality of the welded workpiece can be effectively detected, and a welding defect can be found in real time.
Abstract: A laser welding control method, apparatus and system, and an electronic device are disclosed, the method includes: receiving a current position of a welding head fed back by an encoder; determining whether the current position reaches a set position; and in response to the welding head reaching the set position, sending a laser control signal to a laser device to control the laser device to output laser at the set position.
