What is the lpt inspection

Question

Accepted Answer

LPT inspection stands for Liquid Penetrant Testing, a non-destructive testing method used to detect surface-breaking defects in materials.

LPT inspection involves applying a liquid penetrant to the surface of a material, allowing it to seep into any surface-breaking defects.
After a certain amount of time, the excess penetrant is removed and a developer is applied to draw out the penetrant from the defects, making them visible.
The defects appear as bright, contrasting indications against the developer background, allowing for easy detection and evaluation.
LPT inspection is commonly used in industries such as aerospace, automotive, and manufacturing to ensure the quality and integrity of materials and components.
