Corroded Microstructure

Corroded steel has a damaged surface with flaky, cracked features. This happens due to chemical reactions with air and water.

Physical-Chemical Mechanism of Action

Corrosion is a chemical process where steel reacts with air and water, causing damage. This leaves a rough surface with cracks and pits.

Metallurgical Relevance & Welding Risks

Corroded steel can have weak spots that may lead to cracks or failure during welding. Corrosion also compromises strength and reliability.

Workshop Practice & Instructions

Before welding steel, make sure it's not corroded. Clean it thoroughly to remove dirt and corrosion products. Use chemical cleaners or mechanical methods like sandblasting.
