Western Instruments QQI’s Quantitative Quality Indicators

The Western Instruments QQI’s Quantitative Quality Indicators is artificially flawed low carbon steel specimens that are used in magnetic particle inspection (MPI). They are used to establish, and assuring, the proper magnetic field is achieved to produce indications of flaws in ferromagnetic parts. It must be emphasized that Western Instruments QQI’s Quantitative Quality Indicators are themselves flawed parts, so that when they are placed in an appropriate magnetic field, indications will appear when magnetic particles are applied. Western Instruments QQI’s Quantitative Quality Indicators are manufactured strictly in accordance with applicable AMS specification.
