摘要：
It is shown that in vacuum electron-beam welding of alloys which contain elements with high vapor pressures, the evaporation of these elements causes an extensive additional degassing of the pool. The additional removal of hydrogen caused by the evaporation of the alloying elements may reach 50% in the aluminum alloys.
