Atmospheric Corrosion Testing
The atmospheric corrosion test checks the rusting behavior of materials under natural or accelerated atmospheric conditions. It is carried out through outdoor weathering or laboratory climate tests.
Physical-Chemical Mechanism of Action
The test simulates natural rusting of metals in air by exposing them to a special apparatus. This can be done either outdoors or in a laboratory climate. The process involves the reaction of the metal with oxygen and moisture, leading to corrosion.
Metallurgical Relevance & Risks in Welding
The test results show how well a material withstands various atmospheric conditions. Poor rusting behavior can lead to wear, cracks, and reduced component service life. This is especially important for metals used in humid or salty environments.
Workshop Practice & Action Instructions
To perform the test, the workpiece is placed in a special corrosion test apparatus. This can be set up either outdoors or in a laboratory climate. Test duration varies depending on requirements and can range from a few days to months. After the test, the workpiece is evaluated to determine its rust resistance.
