Title: Innovations by Inventor Dong Fei
Introduction
Dong Fei is a notable inventor based in Peoria, Illinois, with a remarkable portfolio of 16 patents. His work primarily focuses on advancements in welding inspection methods and extending the service life of turbocharger compressor wheels.
Latest Patents
One of his latest patents is a weld inspection method and system. This innovative system inspects a weld on a component with multiple cross-sections. It includes a camera positioned above the weld to optically sense the weld position. A projector above the weld projects a primary scan path onto the component along the weld position. An imaging probe scans the weld while moving along this path, generating a series of 2D cross-sectional images. Each image is optically encoded with the respective position and skew angle of the imaging probe.
Another significant patent is a method for extending the service life of used turbocharger compressor wheels. This method involves inspecting the compressor wheel for material discontinuities, such as fatigue cracks. If no significant cracks are found, the method allows for renewing the compressor wheel through a process like peening. The inspection is conducted using non-destructive examination techniques to ensure the integrity of the component.
