Corroded Residual Volume

Corroded residual volume is the remaining load-bearing cross-section of a component after chemical alteration or material loss due to corrosion.

Physical-Chemical Mechanism of Action

Corrosion is a chemical process where metals react with environmental substances, eating away the material. This reduces the original volume and load-bearing capacity.

Metallurgical Relevance & Welding Risks

Too much corrosion loss can compromise mechanical strength, leading to cracks or failure. It's crucial to treat and clean the material properly before welding to ensure a sound joint.

Workshop Practice & Instructions

Before welding a part, clean it thoroughly. Use chemical cleaners or mechanically remove corrosion. Set and stick to a minimum remaining wall thickness to ensure a safe weld.
