1. Introduction
Welding is an important application technology in the traditional manufacturing industry, and it is also an important method for the production and fabrication of thick plates. Thick plate welding technology has developed rapidly in recent years. Thick plates generally refer to plates with thickness greater than 10mm, and the welding performance of thick plates has a great influence on the safe and reliable use of structural products. Therefore, it is very important to improve the welding performance of thick plate welding.
Oxide metallurgy process are a kind of thermal treatment processes, like high temperature and high pressure process, which have good performance in improving the welding performance of thick plate. Oxide metallurgy process can be used to effectively improve the surface condition and internal structure of thick plate, making the welding quality of thick plate more stable.
2. The effect of oxide metallurgy on the welding performance of thick plates
2.1 Improve the surface condition of weld
The surface condition of weld is closely related to the welding process and the welding performance of welded parts. Oxide metallurgy process can reduce the impurities and inclusions on the surface of thick plate, and the surface will become smoother. In addition, the oxide metallurgy process can reduce residual strain and stress on the surface, which can also improve the welding performance of thick plate.
2.2 Control the shape and size of welding pool
When welding thick plates, the shape and size of the welding pool are essential for the stability of the welding process. Oxidation metallurgy process can adjust the shape and size of the welding pool, so that the welding of thick plates is more uniform and stable.
2.3 Increase the solidification speed of welding pool
When welding thick plate, the solidification speed of welding pool is an important indicator to measure the welding performance of thick plate. With the improvement of oxidation metallurgy process, the solidification speed of welding pool will be improved and the welding performance of thick plate will be improved.
2.4 Change the composition of welding joints
Welding joint is an important part in the whole welding process of thick plate, and the composition of welding joint has great influence on the welding performance of the welded joint. the oxidation metallurgy process can change the composition of weld joint, thus improving the performance of the welded joint.
2.5 Change the crystal structure of welding joint
The crystal structure of welding joint will affect the mechanical properties of the welded joint. With the improvement of oxidation metallurgy process, the crystal structure of welding joint will be optimized, thus improving the performance of welding joint.
3. Conclusion
Oxide metallurgical process is an effective way to improve the properties of thick plate. This process can be used to effectively improve the welding performance of thick plate by improving the welding surface condition, controlling the shape and size of weld pool, increasing the solidification speed, changing the composition of welding joint and changing the crystal structure of welding joint. Therefore, we can conclude that the oxidation metallurgy process has important application value in improving the welding performance of thick plate.
