Abstract
A gas turbine component can be refurbished and/or repaired with an arc welding process that is used in conjunction with a 6-axis robot, a camera and a robot controller/vision processor. Applied to a wire fed plasma welding process, the vision system identifies the part, constructs a weld path based on the part's individual contour, and calculates a trajectory (with or without sinusoidal oscillation) for the robot arm to follow.
