Abstract:
An imaging system for controlling powder (52) aiming into a molten puddle (56). In the imaging system of the present invention, an image processor (94) extracts a first image of the molten puddle (108) and a second image of a powder enveloppe (112) from a composite image of the weld area. The first and second processed images provide feedback for process control.
