Quantification of Surface Edge Cracks

Precise measurement of cracks at surface edges using high-precision techniques and light microscope analysis to ensure operational safety.

Physical-Chemical Mechanism of Action

Cracks at surface edges can be caused by mechanical stress or chemical corrosion. They create stress concentrations and can lead to further damage if not removed.

Metallurgical Relevance & Welding Risks

Cracks at surface edges can be reactivated during welding or new cracks may form. This can lead to hot cracking and brittleness, compromising the safety of the parts.

Workshop Practice & Action Instructions

Use high-precision replication techniques like the replica method or scanning electron microscopy (SEM) to measure cracks. The exact number and size of cracks must be below 10 µm to ensure the parts are safe.
