Abstract
Multisensor information fusion technology in welding process was studied, and Choquet fuzzy integral method was used in this paper to fuse the information obtained by arc, sound, and visual sensors in pulsed gas tungsten arc welding (GTAW) process. A novel method to obtain the fuzzy set function values in fuzzy integral was proposed to obtain the prediction results of single sensor, and a method by using supporting degrees of different sensors was proposed to obtain the fuzzy measure function values in fuzzy integral. Choquet fuzzy integral was used to fuse the information after the fuzzy set function and fuzzy measure values were obtained, and the multisensor information fusion model based on the method was proposed. Experiment was done to test the effectiveness of the method in the end.
