An electron-beam welding operation will join two pieces of steel plate together. The plates are 1.00\nin thick. The unit melting energy is 125 Btu/in3.
An electron-beam welding operation will join two pieces of steel plate together. The plates are 1.00
\r\nin thick. The unit melting energy is 125 Btu/in3. The diameter of the work area focus of the beam is
\r\n0.060 in, hence the width of the weld will be 0.060 in. The accelerating voltage is 30 kV and the
\r\nbeam current is 35 milliamp. The heat transfer factor is 0.70 and the melting factor is 0.55. If the
\r\nbeam moves at a speed of 50 in/min, will the beam penetrate the full thickness of the plates?
