Abstract
A system for supporting, guiding and controlling a welding head to maintain the welding head normal to the instantaneous surface contour of overlapping, convoluted metal sheets to weld the same together. The system is capable of being supported on the convoluted metal sheets regardless of the relative orientation (vertical, oblique or downwardly or upwardly horizontal) of the sheets. In order to maintain a preselected penetration, consistently throughout the welding of the sheets, the orientation of the weld head, the amount of heat developed at the weld head and the rate of speed of travel of the weld head are precisely regulated. The orientation of the weld head relative to the sheet is controlled by a mechanical sensor which activates a preprogrammed configuration device displaying characteristics substantially identical with any particular departure from the normally linear surface of the sheets. With the exception of the departures from the linear portion of the sheets, the system is programmed to proceed linearly according to predetermined conditions.
