Welding Inspection - WELD-CHECK

WELD-CHECK is a fully automatic system for non-destructive, contactless examination of welded joints of car bodies and sets new standards for testing accuracy and efficiency.

Automated Testing System WELD-CHECK

Quality Control and Weld Inspection with WELD-CHECK

  • Universal use through testing of resistance and laser welded joints (resistance welding spots, laser welding seams, RobScan welding seams)
  • Increase in efficiency through fully automatic weld testing system with measurement duration of only a few seconds per welding seam or welding spot
  • Highest weld testing accuracy through evaluation with special software algorithm
  • Detection and classification of various types of defects as deviations in the joining process at an early stage
  • Integration into the local quality management by creating test records to be included into databases

Thermography for Fully-Automated Non-Destructive Testing of Car Bodies

Using pulse thermography, the weld inspection system WELD-CHECK enables you a quantitative assessment of the inspected welds. A special software algorithm analyzes the pulse-induced change in temperature in the tested joint and computes, based on its temporal course and geometric spreading, corresponding test results. These results are documented in a test report and provided in a format that can be used in your quality databases. This makes WELD-CHECK the ideal weld test system for automobile body assembly - both as an offline measuring unit as well as for in-line inspection.

Thermal imaging cameras of the high-end camera series ImageIR ® by InfraTec are essential components used in this system. Enabling a geometric resolution of up to (1,920 × 1,536) IR pixels, frame rates with some kHz and thermal resolutions below 0,015 K they provide the precise measurement basis for the reliable detection of even the smallest anomalies.

Usage of ImageIR® to test laser welds of body components

Quality Assurance with Active Thermography

Non-destructive testing methods are becoming increasingly more important in the industry. One reason is that they cost much less than other test methods. As a very elegant method, the active heat flow thermography method is now firmly established as a powerful method of non-contact and non-destructive testing of products of different manufacturing technologies.
