The TIG Welding Pool Calculator Image Detecting System

The composing and work principle of TIG welding Rapid Prototyping metal fabric system will be introduced in this paper. The best sensor in TIG welding Rapid Prototyping metal fabric is vision sensor that is the result of contrasting all kinds of welding line size information detection sensor.The name of welding craft in TIG welding Rapid Prototyping metal fabric is TIG deposit surfacing welding. Through analyzing the sensor environment, the composing of CCD welding pool vision sensor and hardware position parameters is chosen. The scale of CCD welding pool vision sensor is ensured. According to the demand of TIG welding Rapid Prototyping metal fabric experiments, The TIG weld parameters open loop control system is executed.The common welding pool image processing methods of welding pool calculator image detecting system are introduced in this paper. Base on the character of welding pool, different kinds of welding pool image will be processed, for example: the fixation welding pool image, different character welding pool image of dynamic welding. The welding pool image processing arithmetic is predigested because that the intent of welding pool image processing is getting the breadth of weld seam. The TIG welding pool calculator image detecting system can effectually detect the breadth of weld seam by contrasting the data of detecting with the data of experiment.The initial problem research in TIG welding Rapid Prototyping is estimating surface size parameter of the welding seams. BP nerve network is adopted in text to estimate the surface size parameter of the welding seams base on the character of nerve network. On the foundation of a great deal of experiments, the data of experiments are analyzed and put into the nerve network to carry on the training and the nerve network can elementarily implement the surface size parameter forecast of the welding seams. Using it and the rule of multiplayer welding in experiments, some metal fabric is fabricated.
