Corrosion-Resistant Wire Consumable
A filler material for improving the corrosion resistance of steels, either austenitic or nickel-based. It protects against intergranular corrosion through adjusted chromium and nickel ratios.
Physicochemical Mechanism of Action
Corrosion-resistant filler wire contains special additives such as chromium and nickel that change the surface structure of the steel. These additives create a thin surface layer that provides corrosion protection.
Metallurgical Relevance & Welding Risks
Using a corrosion-resistant filler wire reduces the susceptibility to intergranular corrosion. However, wrong filler material or insufficient dosage can lead to increased weld hardness, which can cause cracks and distortion.
Workshop Practice & Action Guidelines
Select the correct corrosion-resistant filler wire based on the steel being welded. Pay attention to the proper filler amount and the appropriate welding process. If needed, perform post-weld treatment to optimize corrosion protection properties.
