The embodiment of the invention discloses a welding state recognition method and device based on two-channel characteristics and electronic equipment, and relates to the technical field of ultrasonic welding, according to the method, signal obtaining is not conducted on a workpiece, but a two-channel force signal of a welding seat is obtained in real time, and at the moment, the welding state is recognized; frequency domain statistical characteristics of the two-channel force signals are extracted to determine multiple frequency domain statistical characteristics, the multiple frequency domain statistical characteristics are optimized to obtain accurate main characteristics, and the main characteristics are used for state classification and input into a welding state monitoring model to output the welding state in the welding process. Therefore, real-time acquisition of the welding state is realized, full inspection of welding of the workpieces is facilitated, real-time mastering of the welding state of each
