Destructive & Non-destructive test
Destructive test

Destructive testing aims to deform or destroy a material to analyze its point of failure.
On the other hand, non-destructive testing uses inspection methods that do not damage a material or asset in any way.
Inspectors use DT and NDT in different scenarios.
Non Destructive test

Non-destructive testing (NDT) is a testing and analysis technique used by industry to evaluate the properties of a material,
component, structure or system for characteristic differences or welding defects and discontinuities without causing
damage to the original part.
Macro etching test
Metal macroetch inspection is a non-destructive testing technique used to examine the macrostructure of metallic materials.
It involves etching the surface of a metal sample to reveal its macroscopic features, such as grain size,
inclusions, segregation, and discontinuities.
