Question

The defects in the castings are majorly caused by the surrounding environmental conditions.

(a) True

(b) False

This question was posed to me in class test.

I want to ask this question from Classification of Defects & Factors Affecting Salvage of Castings topic in chapter Salvage of Defective Castings of Casting-Forming-Welding I

Answer 1

The correct option is (b) False

The best explanation: The surrounding has negligible affects on the castings. The defects are majorly caused by unsuitable raw materials used in moulding, using improper tools, equipment, patterns. And sometimes faulty organization and lack of training for the workers can also lead to the inducement of defects in the castings.
