The invention discloses a weld joint structure mechanical vibration grain refining device in a fusion welding process, which comprises a small vibration motor for outputting high-frequency mechanical vibration, the vibration is transmitted to a welding part through a vibration contact by a movable section, and the high-frequency vibration is input for the solidification process of molten metal in a molten pool in the welding process. The movable section is provided with a multi-joint metal rod device connected through a bolt, and the shape of the movable section can be flexibly adjusted to be matched with complex and changeable welding parts. The vibration contact is connected to the tail end of the movable section through threads and can be flexibly replaced according to specific working conditions. After the welding work is prepared, the movable section and the vibration contact are adjusted, the vibration contact makes contact with the welding part, in the whole welding work process, it is guaranteed that the vibration contact continuously inputs high-frequency vibration to the welding part, and therefore the purpose of refining a weld joint structure is achieved.
Description
technical field [0001] The invention belongs to the field of welding technology, and relates to a mechanical vibration fine crystallization device of weld seam tissue during fusion welding. Background technique [0002] As one of the key technologies for the connection of metal materials in the process of modern industrial development, welding technology plays a vital role in the performance and service safety of parts with welded structures or large equipment. Because the solidification of molten metal in the welding process, especially the fusion welding process, is different from the traditional metal casting process, there are large temperature gradients, fast cooling rates, unbalanced solidification processes, element segregation, and uneven solidification structures. The weld area in the welded structure becomes the weakest position in the whole part, which leads to the decline of the overall performance of the whole part. [0003] Therefore, how to optimize the weldi...
