Hardness profile analysis

Hardness traversing measures hardness across a weld or case-hardened layer. It shows microstructural gradients and finds brittle or hardened zones.

Physical-Chemical Mechanism

Hardness traversing measures hardness at points along a defined line. It shows how hardness changes across the weld or case layer.

Metallurgical Relevance & Welding Risks

It helps locate brittle or hard zones from uneven cooling. These zones can crack or harden, harming the material.

Workshop Practice & Action Points

Use a microhardness tester. The line should be parallel to the weld or case. Measure at least five points for a representative profile. If uneven, check and adjust cooling conditions.
