摘要: 本发明公开了一种铝合金真空电子束焊接方法,该方法将焊接工件相互压装后放入真空室中;然后以电子束流为4-8mA、扫描频率为80-200Hz、X轴和Y轴扫描幅值为200-300、焊接速度450-60mm/s进行预热;以对缝束流为10-15mA、扫描频率为80-200Hz、X轴和Y轴扫描幅值为200-300、焊接速度450-600mm/s进行定位预连接;再以电子束流为30-45mA、扫描频率为80-200Hz、X轴和Y轴扫描幅值为200-300、焊接速度450-600mm/s进行穿透焊接;最后进行焊缝修饰。本发明焊接方法简单,焊缝质量好、气孔少、焊缝美观,工件变形较小。
英文摘要: The invention discloses an aluminum alloy vacuum electron beam welding method. The method includes: press-fitting welding workpieces and placing the workpieces in a vacuum chamber; preheating with 4-8mA electron beam current, under the scanning frequency of 80-200Hz, X-axial and Y-axial scanning amplitude of 200-300, and welding speed of 450-60mm/s; positioning and pre-connecting with 10-15Ma butt beam current, under the scanning frequency of 80-200Hz, X-axial and Y-axial scanning amplitude of 200-300 and welding speed of 450-600mm/s; performing penetration welding with 10-15mA electron beam current, under the scanning frequency of 80-200Hz, X-axial and Y-axial scanning amplitude of 200-300Hz and welding speed of 450-600mm/s; finally trimming welds. The method is simple, weld quality is good, few pores occur, the welds are attractive, and little deformation of the workpieces occurs.
