Which of the following term is associated with intergranular corrosion

1.	Which of the following term is associated with intergranular corrosion in welded structures?(a) Intergranular weld(b) Weld failure(c) Weld decay(d) Weld corrosionI got this question by my school teacher while I was bunking the class.Question is from Eight Forms topic in section Eight Forms of Corrosion of Corrosion Engineering
Answer» Right choice is (c) Weld decay Explanation: The intergranular corrosion ASSOCIATED with the welded STRUCTURES and METALS is KNOWN as weld decay. The depletion of alloying takes place adjacent to the weld bead as it EXPOSED to high temperature (sensitization temperature).
