Automation: Set up alignment, calibration and programing anyone? What works and what are the limitations of robotics welding? Robotics control the movement of a rotating wrist in a defined space.

Two common kinds of welding robots are: articulating and rectilinear robots. 
Articulating robots employ arms and rotating joints.  These robots move like a human arm with a rotating wrist at the end.
Rectilinear robots manoeuvre the weld arc point along any three axes directions.  In addition to linear movement of the robot along x, y, z axes, is a 'wrist' joint allowing the robot rotational movement.

Many factors need to be considered when setting up a robotics welding system:  • Accuracy  • Repeatability  • No. of axes
 • Programming  • Tracking systems  • Controls
 • Monitors, etc.
