Standard QQI, flaw depth of 30% of Shim thickness, .004" thick. Self Adhesive

Basic circular and crossed bar flaw configuration suitable for longitudinal and circular fields

QQI Test Pieces

Quantitative Quality Indicators (QQI) are Magnetic Particle Test Pieces with Artificial Defects

QQI’s are used:

• to increase productivity by minimizing magnetizing shots
• to verify field direction and relative strength
• to balance multi-directional fields
