Review of intelligent control to welding and its application

Welding is a complicated metallurgical process.Because prolific information can be got from the welding pool,the research on the sensing and control of the welding pool is one of the important fields in welding.The applications of artificial intelligeuce( AI) technology,such as artificial neural network,fuzzy logic,in welding field including processes control,parameters selection,prediction of seam shape,online information technology,property and defect prediction were summarized,at the same time the merits and defects among the different ways were compared.Moreover,some existing problems in the application of AI technology and its development direction in the welding were also discussed.
