Abstract
The occurrence of ripples on the workpiece surface after solidification in electron-beam weld or melting is experimentally and analytically investigated. The maximum accelerating voltage and welding current of electron-beam welder are 60kV and 50mA, respectively, while the workpieces are four different materials containing different quantities of sulfur. Using a scale analysis to account for heat transfer and fluid flow induced by different quantities of surface active element in the molten pool. The result predicted results show good agreement with experimental data.
