Answer Details

The type of iron that is best suited for welding, making nails, chains, and iron rods is wrought iron. Wrought iron is a soft, malleable, and ductile form of iron that contains very low carbon content. Its low carbon content makes it easier to shape and weld without becoming brittle, which is why it's often used in construction applications where high strength is required. In contrast, pig iron, cast iron, and iron pyrites are not suitable for these applications due to their higher carbon content and brittleness.
