Spot welding continues to be a robot application mainstay. This video from KUKA Robotics – one of the major brands seen at Automate 2011 – reminds us how this traditional application still matters today and how new developments happen in old categories.
Now KUKA has a new arc welding robot, the KR 5 ARC HW (Hollow Wrist) that takes the rugged design of through-the-wrist cabling to a new level.
The 50 mm opening in the arm and wrist, for example, allows the arc welding dress package to be routed in the protective interior of the arm. This not only shields the dress package from mechanical influences, but also prevents undesirable whiplash motion during reorientation of the robot. Both torsion-type dress packages and infinitely rotating arc welding dress packages are possible. For the user, this means not only improved component accessibility and optimal protection of the dress package, but also simplified offline programming.
