Abstract

The invention belongs to the field of welding, and particularly relates to a magnetic shielding system for electron beam welding. The magnetic shielding system comprises a detecting portion, a shielding cover body and a control portion. The structure of a shielding cover can be adjusted according to the complexity degree of electron beam processing and the intensity of an environmental magnetic field, and an electric ejector rod is controlled to enable inner and outer layer silicon steel sheets to be nested and combined into a single layer structure or a multi-layer structure, so that different shielding requirements are met, a stable trajectory is ensured during electron beam processing, and welding precision is high.

Description

technical field [0001] The invention belongs to the field of welding, in particular to a magnetic shielding system for electron beam welding. Background technique [0002] The electron beam welding technology of one gun and multiple beams is to make the electron beams move rapidly at different positions through the control of the magnetic field. Due to the high frequency of movement, the effect of multiple beams is generated, so as to process and process the material or structure. Vacuum electron beam welding has extremely strict requirements on the magnetic field, and the moving charge will be disturbed by the environmental magnetic field or the magnetic field of the workpiece, and the trajectory will be deflected. The patent CN105228433A of Xi'an Aviation Power Co., Ltd. provides a magnetic field shielding method, but this method is only suitable for single-beam electron beam processing. Contents of the invention [0003] The invention provides a magnetic shielding syst...
