The invention belongs to the technical field of part connection design, and particularly relates to a part connection method. The part connection method comprises the following steps of gathering metal powder on the surface of a molten pool of connected parts by adopting a laser deposition forming technology, and melting and depositing the metal powder among the connected parts layer by layer to realize connection among the connected parts. According to the part connection method, connection between the connected parts is achieved based on the laser deposition forming technology, the connectedparts are connected into a whole in a laser deposition fusion mode, the number of parts can be greatly reduced, stress concentration is eliminated, load transmission is more uniform, and in addition,connection between the connected parts is achieved based on the laser deposition forming technology; and the melting deposition process of the metal powder between the connected parts is similar to the forming process of the connected parts, so that the connected parts are compact in structure, small in heat affected zone and good in mechanical property, and fatigue weak links can be reduced.
Description
technical field [0001] The present application belongs to the technical field of component connection design, and in particular relates to a component connection method. Background technique [0002] The connection between components in the current project is mainly realized in the following two ways: [0003] 1) Welding connection, the parts are connected in this way, the heat-affected zone of the weld seam is relatively large, the welding thickness is limited by the size, the fatigue performance is poor, and the allowable stress is low; [0004] 2) Set up a process separation surface between the components, connect the components through centralized joints, and connect the components in this way. The load transfer goes through the process of dispersion-concentration-dispersion, which is prone to stress concentration and requires more parts to be designed , there is a large weight redundancy. [0005] In view of the existence of above-mentioned technical defect, propose t...
