Product Name: Quantitative Quality Indicator (QQI) Test Gauge

Short Description: Enhance the accuracy of magnetic particle inspection with the QQI Test Gauge, designed to assure proper field direction and field strength during non-destructive testing processes.

Detailed Description:

The Quantitative Quality Indicator (QQI) is an essential tool for verifying the magnetic field direction and intensity during magnetic particle inspections. Often used in aerospace, automotive, and manufacturing industries, QQIs help ensure that components are inspected correctly using the wet method of continuous magnetization.

Types of QQIs:

• KSC 230 STANDARD QQI: Features a basic circular and crossed bar flaw configuration suitable for longitudinal and circular fields, with a flaw depth of .0006 inches (30% of shim thickness).
• KSC 4-230 MINIATURE QQI: A smaller version of the KSC 230, designed for testing small areas. These can be cut into four separate circles for individual use.
• KSCT 234 VARIABLE DEPTH QQI: Offers three concentric circular flaws of differing depths (.0004", .0006", and .0008") for more detailed quantitative analysis.

Usage Instructions:

To use, place the QQI on the part being inspected, etched side down, and secure it with tape or glue. After magnetizing the component and applying magnetic particles, the adherence of particles over the engraved patterns indicates adequate field strength and correct direction. The multidirectional technique shows a balanced field when all areas of the QQI display indications.

Advantages:

• Provides a quantifiable means to adjust and validate the magnetic field during inspections.
• Reusable with careful application and removal, suitable for various configurations with proper selection.
• Ensures balanced field intensity and direction in multiple-direction magnetization equipment.

Considerations:

• The application process requires clean and dry parts, and the setup time can be extensive.
• Shims are delicate and must be handled with care to avoid damage and corrosion; they must be cleaned and stored properly after use.

This QQI Test Gauge is an indispensable tool for professionals in industries where precise non-destructive testing is crucial for maintaining high quality and safety standards.
