Problems solved by technology
[0002] The existing large-scale thin-walled high-strength aluminum alloy circular components have low weld performance, and the commonly used heat treatment aging process does not have a furnace large enough to accommodate super-large-scale components, so it is difficult to achieve aging heat treatment of large-scale components, and it is difficult to control large-scale thin-walled components. In order to solve the above-mentioned problems, it is necessary to design a device and method that can solve the above-mentioned problems due to the thermal deformation caused by the aging treatment of components and the over-aging of the base metal during the aging treatment.
