ABSTRACT:
A guidance system for an automatic welder. A probe having a casing with a concentric actuating rod supported in the casing by means of a pivot plate which is movably mounted on a fixed plate. A probe finger is attached to the lower end of the actuating rod. The upper end of the actuating rod passes through a series of switches which sense movement of the actuating rod in horizontal and vertical planes. Additional switches provide a means for biasing the probe for movement in a given direction without receiving any external signal and effecting two speed travel of the unit. Control relay coils are actuated by the switches resulting in the actuation of motors moving the guidance and welding systems until new information is received from the probe.
