Question

Better surface finish and grain structure of material are the main advantages of using the swaging process.

(a) True

(b) False

I have been asked this question during an interview for a job.

This intriguing question originated from Swaging in section Miscellaneous Forming Processes of Casting-Forming-Welding II

Answer 1

Right choice is (a) True

To elaborate: In the swaging process, hammering action is produced which provides better surface finish, tensile strength and better grain structure to the material. In this process, the work-piece should be completely clean and dry, and without any kind of lubricant. This method is very simple and can be performed by any unskilled operator.
