Question

Destructive testing method can also be economical for large casting or structure.

(a) True

(b) False

This question was posed to me in unit test.

My enquiry is from Destructive Testing in chapter Inspection Testing in Foundries of Casting-Forming-Welding I

Answer 1

Right choice is (b) False

To elaborate: Destructive testing method can be applicable to the large structures but it is not economical because destruction of large casting or structure will cause steep downing of productivity. So for large structures or castings, other methods are used for the inspection like modeling by finite element software.
