Namely: a two-device welding quality management system based on artificial intelligence technology carries out welding quality management on two devices through a quality management platform, and the two devices needing to be welded are collected through a data collection unit; real-time environment detection is carried out through an environment analysis unit; analyzing the welding materials required in real time through a material analysis unit; predicting through an operation prediction unit, if the prediction is qualified, generating an operable signal and sending the operable signal to a server; detecting the operation of the welding machine in the welding process through a welding machine analysis unit; and analyzing the welding seam generated by welding through a welding seam analysis unit, constructing a welding detection model through a welding detection unit, and detecting the welding quality.

The above formulas are all calculated by taking the numerical value of the dimension, the formula is a formula which obtains the latest real situation by acquiring a large amount of data and performing software simulation, and the preset parameters in the formula are set by the technical personnel in the field according to the actual situation.

The foregoing is merely exemplary and illustrative of the present invention and various modifications, additions and substitutions may be made by those skilled in the art to the specific embodiments described without departing from the scope of the invention as defined in the following claims.
