柔性薄壁结构电子束焊接的变形控制

Deformation Control of Thin-Walled Structure Welded by Electron Beam

基于电子束焊接方法,探讨了功率分出轴柔性薄壁结构真空电子束焊接过程中的变形控制方法,提出了综合应用最小焊接热输入、减小焊接重叠角度和合理焊接装配及散热相结合的变形控制方法,有效地控制了焊接变形,实现了电子束焊接柔性薄壁结构的制造。

Based on electron beam welding method, the deformation control method of vacuum elec-tron beam welding process of PTO flexible thin-walled structures is explored. The deformation control method combined with comprehensive application of the minimum weld heat input, reducing the overlap angle, reasonable welding assembly and heat radiation is proposed. The welding deformation is controlled effectively and the man-ufacturing of PTO lfexible thin-walled is achieved by using electron beam welding.
