摘要：

Estimation of Laves phase was done in alloy 718 electron beam welds prepared with and without beam oscillation. As relatively higher heat input was used in preparing beam oscillated welds, the full benefits of beam oscillation in producing welds with lesser amount of niobium segregation and lower amount of Laves phase could not be realized.
