Automated detection of cracks, tears, and edge splits during rolling and processing.
Global Gauge’s Edge Crack Detection System provides automated inspection of strip edges during rolling or processing operations. Using high-resolution vision technology, the system identifies cracks, tears, or edge splits that could compromise downstream processing or final product integrity.
High-resolution line-scan cameras capture both strip edges at full mill speed.
Vision software identifies cracks, tears, and splits using trained pattern recognition.
Each defect is geo-tagged on the coil so downstream processes can trim or downgrade with precision.
Operators receive real-time alerts; shift reports include defect counts and severity.
