Magnetic Pie Gauge Magnetic Particle Field Indicator for NDT Magnetic Particle Testing

The 1# indicator is a combination of eight triangular pieces. One side features a brass surface, while the other side features eight line surfaces.

• Hold the handle during use and keep the brass side facing upward.
• Keep the eight-line surface facing downward and close to the workpiece surface.
• Apply the continuous method for magnetic inspection.
• Spray magnetic suspension to clearly display the magnetic image.

The 2# indicator is a combination of eight triangular pieces, with both sides featuring a brass surface.

• Hold the handle during use and keep either brass surface facing upward.
• Close the indicator to the workpiece surface.
• Apply the continuous method for magnetic inspection.
• Spray magnetic suspension to clearly display the magnetic image.

The 3# indicator is a combination of four triangular pieces. One side features a brass surface, while the other side features four wire surfaces and two round dots.

• Hold the handle during use and keep either brass surface facing upward.
• Close the indicator to the workpiece surface.
• Apply the continuous method for magnetic inspection.
• Spray magnetic suspension to clearly display the magnetic image.
• Verify whether the flaw detection equipment, comprehensive performance, and operation method of the magnetic suspension are appropriate.
• Adjust the distance between the cover and soft iron to find certain magnetic field values, then observe the limit value of near-surface defect buried depth capability.
