Problems solved by technology

However, if the above-mentioned 6061 aluminum alloy is welded directly by the ordinary vacuum electron beam welding method, there will be defects such as many pores inside the weld, poor surface formation, and severe spatter, resulting in poor sealing of the welded joint and low tensile strength, which is difficult to meet the design requirements.

Abstract

The invention discloses an aluminum alloy plate vacuum electron beam welding method, a flange and an X-ray image intensifier. The method comprises the steps of positioned welding, penetration fusion welding and the like. The flange comprises a 6061 aluminum alloy plate which is formed into a whole by the aluminum alloy plate vacuum electron beam welding method, and the X-ray image intensifier uses the flange. According to the welding method, welding between 6061 aluminum alloys is stable, the width of a welding seam is uniform, splashing is small, and the welding method has the characteristics of few pores in the welding seam and high tensile strength. The flange manufactured after welding and the large X-ray image intensifier applying the flange have the advantages of stable performance, long service life and the like due to the effects.

Description

technical field [0001] The invention relates to a welding method, in particular to a welding method of a flange in a large X-ray image intensifier. Background technique [0002] In order to ensure the lightweight and portability of the large X-ray image intensifier, the flange needs to be made of high-strength aluminum alloy material, and several 6061 aluminum alloy plates need to be tailor-welded into a ring flange for use during manufacture. [0003] However, due to the high thermal conductivity of the aluminum alloy material, it is impossible to directly weld the above-mentioned aluminum alloy plate. Usually, it is necessary to open a large-angle groove, and at the same time preheat to about 100°C, and perform multi-layer and multi-pass welding at high temperature. Not only is the labor intensity high, but also because the aluminum alloy in a liquid state has strong air absorption and certain oxidative properties, defects such as cracks, inclusions, and pores are prone to...
