Q1: The phenomenon of weld decay is found in case ofA gun metal
B brass
C stainless steel
D cast iron
ANS:D - cast iron Cast iron is not typically associated with the phenomenon of weld decay. Instead, it is commonly known for its own unique characteristics and challenges in welding. Cast iron is a ferrous alloy known for its high carbon content, typically between 2% and 4%, along with silicon and other alloying elements. When cast iron is welded, it presents several challenges due to its high carbon content and the formation of graphite flakes or nodules within its microstructure. Here are some key points about welding cast iron:
