An electron-beam welding operation is to be accomplished to butt weld two sheet-metal parts that
\r\nare 3.0 mm thick. The unit melting energy = 5.0 J/mm3. The weld joint is to be 0.35 mm wide, so
\r\nthat the cross section of the fused metal is 0.35 mm by 3.0 mm. If accelerating voltage = 25 kV,
\r\nbeam current = 30 milliamp, heat transfer factor f1 = 0.85, and melting factor f2 = 0.75, determine
\r\nthe travel speed at which this weld can be made along the seam
