抄録
The effect of activating flux in electron beam welding was investigated, and the activating electron beam welding (A-EBW) was proposed. Results clearly showed that activating fluxes affected the penetration capability of electron beam welding for stainless steels. Significant improvement in penetration was observed when electron beam welding was performed both in the conduction mode and the keyhole mode. One of the most likely reasons for the penetration improvement is that the oxygen content through the flux in the weld pool plays an important role in increasing the weld penetration by the reversing of the surface tension gradient in the weld pool from a negative value to a positive value. The change in the surface tension gradient in the weld pool is considered to be the principal mechanism for increased penetration of electron beam welding.
