Problems solved by technology

[0002] The steam generator of nuclear equipment often contains tens of thousands of tube bundles. The tube bundle seal welds undertake the key division area of ​​the primary circuit and the secondary circuit. High quality welds are required. Nuclear power equipment manufacturers at home and abroad all use manual welding torches for mechanical welding. The sealing welding of the tube bundle is performed, the welding quality is unstable, the weld seam is difficult to observe, and the welding efficiency is low
Among the many factors affecting the quality of seal welding seam, the human factor has a great influence on the quality of seal weld, which seriously restricts the weld quality and product manufacturing progress of steam generator tube bundle seal welding

Abstract

The invention provides a tube bundle seal welding full-automatic system, which belongs to the field of mechanical automation products, and comprises a positioning device, a welding device, a welding device and a control device, and is characterized in that the positioning device is used for positioning each tube hole in a tube bundle assembly; the welding device is used for welding tube bundles in the tube bundle assembly one by one according to a preset welding track; the processing device is connected with the positioning device and is used for receiving a preset welding track of the tube bundle, which is transmitted by the positioning device and is used for positioning the position of each tube hole in the tube bundle assembly, and sending out a control signal according to the position information of each tube hole in the tube bundle assembly; the welding device is controlled to seal and weld tube bundles in the tube bundle assembly one by one according to a preset welding track, seal welding of the tube bundle assembly is completed, meanwhile, a series of operation procedures of positioning, seal welding, polishing and cleaning and detection can be efficiently completed, the labor cost and the seal welding operation risk are reduced, and the welding efficiency is improved. And the quality and efficiency of tube bundle sealing weld joints are improved.

Description

technical field [0001] The invention relates to the field of mechanical automation products, in particular to a fully automatic system for tube bundle sealing welding. Background technique [0002] The steam generator of nuclear equipment often contains tens of thousands of tube bundles. The tube bundle seal welds undertake the key division area of ​​the primary circuit and the secondary circuit. High quality welds are required. Nuclear power equipment manufacturers at home and abroad all use manual welding torches for mechanical welding. Carrying out the sealing welding of the tube bundle, the welding quality is unstable, the weld seam is difficult to observe, and the welding efficiency is low. Among the many factors affecting the quality of seal welding seam, the human factor has a great influence on the quality of seal weld, which seriously restricts the weld quality and product manufacturing progress of steam generator tube bundle seal welding.
