Online Eddy Current Flaw Detection System for Flat Copper Strips

Advanced Metal Flaw Detection System

System Configuration & Setup

1. Adjustable Probe Mounting: Flat probes are installed on supports with vertical and horizontal adjustment capabilities.

2. Optimized Gap Control: Guide wheels at both ends of the support can be individually adjusted to maintain the ideal gap between the flat probe and copper bars, maximizing sensitivity while keeping the gap as wide as possible.

3. Stable Material Transport: Drive guide wheels support and transport flat copper bars while restricting lateral movement for precise detection.

 Applications & Detection Methods

Standard Testing (For Regular Shapes)

- Through-Type Probes: Ideal for offline or online inspection of various metal materials including bars, seamless tubes, welded pipes, and strips with different cross-sections (round, hexagonal, rectangular, and square).

- Detection Capabilities: Surface, near-surface, internal surface, and internal defects.

- Process: Materials pass through the probe's inner hole for straight-line transmission testing.

 Specialized Testing (For Large Diameters)

- Saddle-Type Configuration: For high-frequency welded pipe inspection, featuring saddle-type magnetic saturators and probes.

- Defect Detection: Identifies incomplete welding, inclusions, sand holes, air holes, internal burrs, and internal weld nodules.

 Complex Surface Testing
- Point Probes: For materials with large surface areas or complex shapes (crankshafts, automotive components, turbine blades).

- High-Precision Applications: Turbine shaft center holes, metal parts, aircraft bolt holes.

- Methods: Manual operation or automated scanning devices for point-by-point inspection.

System Advantages

- Flexible Configuration: Different detection methods can be equipped with various auxiliary devices.

- Integration Capability: Leverages existing equipment at production sites with custom auxiliary devices.

- Portable Solutions: Simple, lightweight auxiliary devices for mobile inspection sites.

- Operational Options: Both automated and manual operation modes available.

This advanced system delivers precise, reliable detection across diverse metal materials and shapes, with customizable configurations to meet specific industrial requirements.
