Laser Vision Technology
Ensures Six Sigma-level Quality is
Achieved in Robotic Welding
By Jeffrey Noruk and Jean-Paul Boillot
Laser vision systems have a place in robotic welding before, The best time to identify problems is actually at the design-for-
during and after a weld is made. The earlier in the process a manufacturing (DFM) stage, when one looks at the stack-up of
potential problem can be identified, the easier and less expensive tolerances resulting from the detailed part manufacturing and the
it is to fix. assembly methodology. In arc welding, if the joint repeatability of
+/- cannot be maintained, one then needs to consider seam
