Metals Industry
On-Line Detection, Identification, and Visualization of Metal Defects

AMETEK Surface Vision has become the most trusted surface inspection system for metals worldwide. With more installations on more lines than any surface inspection system ever, our systems are relied upon around the world by virtually every major flat rolled products producer. For many of them, we are the de-facto standard in on-line defect detection and identification.

The AMETEK Surface Vision system detects irregularities or defects on the surface of the metal strip. We then identify each defect using our patented SmartLearn® Multi-Step Classifier. The defect image is displayed for the operator to see. All information and images are available in real time, and can be stored in our database for future use. Reports can be created and formatted to fit the needs of every mill.

Our Value

AMETEK Surface Vision provides more value to users than any other surface inspection system. Our systems:

  • Improve product quality
  • Maximize yield
  • Detect, identify, and visualize defects before value added processes
  • Reduce the need for manual inspections
  • Provide the reports you need in a form you can use
We have been successfully inspecting metals surfaces for two decades. In fact, our systems inspect over 1 billion square meters of metal every day! We have metals customers on all continents and more metals customers worldwide than anyone else in the industry. More companies guarantee their quality with AMETEK Surface Vision systems than any other surface inspection system on the market today.

Our Detection

The AMETEK Surface Vision Metals system is highly modular, allowing the use of appropriate technology for your application using standard system components. We install appropriate light and camera configurations for each line. Some allow strip inspection while going over a roller and others allow inspection on the unsupported strip. AMETEK Surface Vision offers the most comprehensive selection of lighting solutions in the industry, applying collimated, diffuse, or side lighting depending on your application needs. For example the use of collimated light allows us to employ our exclusive synchronized view technology with two sets of cameras looking into the surface from different angles. In addition, our collection of thresholding algorithms can be optimized for your particular surface and requirements, all performing on-line in real time. You never have to wait for results.

Our Classification
The SmartLearn® Multi-Step Classifier is a patented classification tool set for AMETEK Surface Vision inspection systems. SmartLearn provides the flexibility to implement classification schemes tailored to your particular process and requirements. The advanced SmartLearn architecture allows the use of various learning classifiers. Combining automatic learning classification with expert knowledge, SmartLearn maximizes the potential of your inspection system for improved product quality, higher production yield, and decreased customer returns.

Our Through-Process Visibility

The Windows®-based AMETEK Surface Vision Metals inspection system, connected to your mill network, provides information for mill-wide users, from the manufacturing floor to the front office. Our solution uses industry standards like OPC and ODBC to ensure easy integration with other plant business, production, and quality systems. A real-time operator interface shows current inspection results on-line all the time. The Open Network Inspection Viewer, distributed across the plant network, enables any user to view current or historical inspection results remotely from any step in production from hot mill to the finishing line.


AMETEK Surface Vision Systems Can Do More

AMETEK Surface Vision users can easily upgrade their system with powerful capabilities that are not available anywhere else.

Our Surface Quality Monitoring software automatically measures and reports the surface quality characteristics of the coil in real time. For the first time, you can have a measurement of overall surface properties such as spangle, cloudiness, roll chatter marks, or surface roughness. It can even predict post-processing properties of the product when it is being produced.

Streaming Video can combine defect detection with full-width video recording of the strip. Watch in real time or go back and replay any archived coil to virtually inspect the strip. All this is done with standard cameras and lighting.

Metal manufacturers face ever-increasing demands to improve quality, increase productivity and create certified defect free products, especially from end-user markets such as the automotive and aerospace industries. This makes a flexible, customizable surface inspection solution essential when optimizing quality and yield.
