Welding fixtures and workpiece manipulators hold
and position parts to ensure precise welding by the robot. The productivity of the robot
welding cell is speeded up by having an automatically rotating or switching fixture,
so that the operator can be fixing one set of parts while the robot is welding
To be able to guarantee that the electrode tip and the tool frame are accurately known
with respect to each other, the calibration process of the TCP (Tool
Center Point) is important. An automatic TCP calibration device facilitates this
time consuming task.
