HUABAO welding stress relief device's Application in Aero Engines...........

Residual stress control in welded components of aero engines is extremely stringent, with an industry saying that an aircraft must not take off with stress. After more than a year of various performance tests, Plant 410 has proven that HUABAO stress-relief technology fully meets the requirements for eliminating residual stress in welded components of aero engines. This technology can be applied to both the production and maintenance of engines. Due to the narrow structural space and high-strength thin plates of the base material in aero engines, no treatment marks are allowed on the surface of parts. Therefore, according to the requirements of Plant 410, a specialized HUABAO stress-relief technology was developed for aero engines, and it has been well applied in this plant and other aero engine maintenance plants.........
