Question

In the electron beam technology, no any cleaning operations are required for the finishing of metal parts.

(a) True

(b) False

This question was posed to me during an interview.

Origin of the question is Laser and Electron Beam Melting With Rapid Prototyping in section Casting Process of Casting-Forming-Welding II

Answer 1

Right answer is (b) False

The explanation is: In the electron beam technology, when the whole process from CAD software to metal formation is completed, then the net shape metal part can be cleaned and finished by any conventional methods. Finishing and cleaning are very necessary and important for a casting to be used in applications.
