Abstract

The invention relates to a tool capable of applying a pressure to carry out electron beam auxiliary heat action connection. The invention relates to a welding fixture for an electron beam auxiliary heat source action connection method. The invention aims to solve the problems of serious metal fire waste, interface reaction and the like, which are generated when a conventional fusion welding technology is adopted to process certain materials, so as to provide the tool capable of applying the pressure to carry out electron beam auxiliary heat action connection. The tool capable of applying the pressure to carry out electron beam auxiliary heat action connection is formed by a fixture housing, a fixture base, a vertical fixing device and a horizontal fixing device. The tool has the following working principle that the welding fixture disclosed by the invention is used by applying a certain pressure to a contact surface of a base metal, simultaneously utilizing a defocused electron beam to carry out circular scanning on a weld joint, repeatedly scanning in a reciprocating manner and controlling the welding speed so as to implement effects of raising the welding temperature and prolonging the heat preservation time, i.e. the defocused electron beam is used as a heat source to implement local connection of the base metal. The tool belongs to the field of a welding auxiliary tool.

Description

technical field

[0001] The invention relates to a welding fixture for an electron beam assisted heat source action connection method, which belongs to the field of welding auxiliary tools. Background technique

[0002] For some materials, such as composite materials, it is difficult to achieve excellent connection effects by traditional fusion welding methods, which will cause serious metal burning and interface reactions. In addition to heating the parts, it is also necessary to heat the weldment as a whole, which will exert additional heat on the base metal of the weldment and affect the overall performance of the base metal. Therefore, it is considered to only carry out local thermal action connection on the welded joints, without welding and heating the base metal as a whole. This requires the use of high-energy-density welding methods with small heat source action areas, such as laser welding and electron beam welding. However, the existing high-energy welding equipmen...
