Basic Understanding of Weld Corrosion - ASM …

Because cast iron is anodic to the high-nickel weld deposit, corro- sive attack occurs in the cast iron adjacent to the weld deposit. It is suggested that cast iron welds made with high-nickel deposits be coated (painted) to reduce the susceptibility to selec- tive corrosion attack.

An Intro to Pipeline Corrosion and Coatings

Intergranular Deterioration. Intergranular deterioration refers to the selective deterioration at a surface's grain boundaries (due to high temperature) when the grain boundary reaches high activity, which is prone to corrosion. Heat treatment and welding heat can cause this transformation, leading to corrosion.
