Ultrasound and liquid penetrant (LP) are used to detect surface and subsurface flaws in metal materials.
Crack detection using ultrasound and liquid penetrant (LP) is a common practice in the industry to identify surface and subsurface flaws in metal materials. Ultrasound is utilized to detect internal flaws, while penetrating liquid is applied to the surface to reveal surface cracks that may not be visible to the naked eye. These combined techniques offer a comprehensive approach to crack detection in critical parts and components.
