Corrosion Buffer
A corrosion buffer is an additive that stabilizes pH fluctuations and prevents the ingress of aggressive chemicals. This protects against localized corrosion.
Physical-Chemical Mechanism of Action
A corrosion buffer works by keeping the pH of a system constant. It reacts to acids and bases to maintain a stable chemical environment.
Metallurgical Relevance & Welding Risks
Without a corrosion buffer, pH fluctuations can cause localized corrosion, damaging the material and shortening weld life. This can lead to cracks and loss of strength.
Workshop Practice & Action Steps
Use a corrosion buffer in the weld zone to minimize pH swings. Make sure the buffer has a pH between 6.5 and 7.0. Check the pH regularly and adjust the buffer concentration as needed.
