Surface Topography Analysis
Surface topography analysis is an optical or tactile measurement of microstructures on metal surfaces to determine bearing ratio and waviness. It is used for quality control after shot peening.
Physical-chemical mechanism of action
Surface topography analysis measures the microscopic structures on the surface of metals. Both optical and tactile methods are used to determine parameters such as bearing area and waviness.
Metallurgical relevance & welding risks
This analysis is critical for quality assurance of weld surfaces. Uneven or defective structures can reduce load-bearing capacity and lead to crack formation. Accurate analysis helps prevent problems such as porosity or uneven weld fusion.
Workshop practice & action items
Use high-resolution optical microscopes or tactile profilometers for measurement. Perform measurements immediately after welding to capture the current surface structure. Use a consistent measurement method and compare results with the specific quality standards for the material being used.
