ABSTRACT:
An apparatus for guiding a welding torch along a weld groove has a visual sensing system for detecting the weld groove cross sectional configuration and relative position of the edges of weld groove. The positional and cross sectional information is assimilated under microprocessor control to actively guide the welding torch through the control of a series of servo motors and adaptively position the welding electrode at an optimal preselected location with the weld groove.
