Non-destructive equipment for residual stress

Residual Stress Test AIS3000 (Advanced Indentation System 3000) is portable indentation system for non-destructive residual stress evaluation. Residual stress in a material shifts the indentation load-depth curve. The load-depth curve shifts to right or left side when tensile or compressive residual stress is applied, respectively. The lower load is needed to reach the same depth when the tensile residual stress is applied, and the higher load when compressive residual stress Therefore, AIS3000 can measure quantitative values for residual stress if it know the relationship between the load gap and residual stress.

Residual Stress Test AIS3000 is made up of a main body and a laptop with software. The AIS3000 can help users perform fast and easy tests with wireless communication module between the laptop and main body. And it is light and miniaturized for easy and fast transportation and installation. Especially, changes in residual stress such as weldment/HAZ/base metal and local material degradation can be analyzed immediately by the superposition of the obtained curves.
