Question

Which of the following devices is used for generating the electron beam in electron beam melting process?

(a) Beam striker

(b) Beam laser

(c) Electron beam gun

(d) Electron runner

I have been asked this question during a job interview.

I would like to ask this question from Laser and Electron Beam Melting With Rapid Prototyping topic in portion Casting Process of Casting-Forming-Welding II

Answer 1

Right choice is (c) Electron beam gun

Best explanation: In electron beam melting process, the electron beam is generated by a device called electron beam gun which is generally located at the top of a vacuum chamber. The Electron Beam Gun is fixed and the beam is deflected to arrive at the desired area, which can melt the metal to form the desired shape of metal parts.
