High Levels of Quality Control Made Possible throughAutomation of Weld Bead Inspections

■Fully automated from scanning through to 3D analysis and pass/fail judgment

Scanning with a 3D camera Creation of the 3D shape Drawing of a judge line and cross-sectional analysis

Automatic pass/fail judgment (conceptual image)

●An accurate 3D shape is created based on combining robot coordinate information and scanned data.●Since a judge line is drawn on after the 3D shape is acquired, analysis on optional section lines is possible.●Pass or fail is judged based on absolute values (dimensions) instead of relative comparison.

■Judgment items can be set according to various inspections.■Data can be stored and output, enabling traceability requirements to also be met.

There are more than 20 inspection items, such as leg length and weld length, enabling various needs to be responded to.

CORETEC’s unique innovative technology for realizing “Absolute Quality”

Accurate 3D shape creation for accurate analysis of welded partsCORETEC’s “3D weld inspection system” constantly acquires robot coordinate information, making it possible to acquire accurate 3D shapes regardless of changes in the robot motion and posture. It can also easily superimpose multiple 3D shapes.

Changes in scanning speed cause deviations to appear.

■Equipped with 3D composition featureSince each 3D shape has robot coordinate information, multiple 3D shapes can be easily composed.

Patented analysis feature that doesn’t depend on scan directionThe “3D weld inspection system” conducts cross-sectional analysis by drawing a judge line after the 3D shape is acquired. Accordingly, since there is no need to accurately trace the welded part or force the robot to conduct complicated movements, merits such as easy teaching and shortened cycle time are realized.

3D shape

Since a judge line (route line) is drawn on after the 3D shape is acquired, analysis can be conducted on optional section lines.Teaching is also simple, regardless of the scan direction. The generated 3D shape is easy to recognize as it is the same as the actual shape.

Company A’s inspection system (example)

Since the section lines are set during scanning, it is necessary to align the camera direction and posture with the route lines on the welded part, thus making the teaching more complicated.Moreover, if curves and spiral shapes are included, not only will the 3D shape differ from the actual shape, but scan time will be impacted.
