The quality of aircraft forged parts largely depends on whether or not cracks appear during the manufacturing process. Here we take an aviation company as an example to illustrate its measures in preventing crack generation during aircraft forged parts production.
The company utilizes a variety of technical means to prevent and control the occurrence of cracks. Firstly, in the selection of materials, the company focuses on selecting high-quality aluminum alloys with uniform chemical composition and suitable heat processing properties. Secondly, during the forging process, scientific process parameters are applied, especially in correctly controlling the temperature, hammering force, and rate parameters to avoid stress concentration during the forging process that leads to various damages on the surface and interior of the part, resulting in cracking. In addition, the company also uses non-destructive testing techniques such as ultrasonic testing, X-ray inspection, and so on, to conduct comprehensive inspections to ensure that the parts have no cracks or other damages.
In specific production, this aviation company employs various anti-cracking technical measures, such as heat treatment and machining. For example, in the free forging process, the company uses appropriate heating and cooling processes to further reduce the stress caused by forging, and enhance the crack and fatigue resistance of the parts through heat treatment. At the same time, the precise machining of the part’s surface can effectively reduce the generation of cracks by removing burrs.
In summary, the company adopts multiple comprehensive and scientific measures to prevent crack generation, ensuring the production of high-quality and safe aircraft forged parts, making significant contributions to aviation safety.
