3D Laser camera improves welding quality at Daimler-Chrysler

Keywords: Laser welding

Two robotic arc welding systems at Daimler- Chrysler, Pillette Rd plant in Windsor, Ontario, complete approximately 300 cross-member assemblies a day on RAM full-size vans. Before the Servo-Robot SF-080 3D laser seam-finder was installed, about 30 per cent of the welding parts needed rework due to sub-components positioning and manufacturing tolerance.

In the Fall of 2001, the first SF-080 system was integrated on the left-hand cell by Nachi robotics to measure the position of the different joints of the part before welding starts. On the initial tryout, the sensor measured positioning errors of up to 4 mm. The routines developed by Nachi Robotics are using this information to automatically offset the robot path for each part. The implementation of these routines has dramatically decreased the rework rate on these parts.

Following this major improvement, John Advoulos, Weld Process Specialist decided to go forward with the installation of a second system on the right-hand cell in 2002.
