Abstract
Means to control the speed of correction of a probe, and a slave such as a torch or welding head, for a welding guidance system, and the like, wherein the response of the probe controls or actuates a device, which is responsive to a predetermined electrical condition, characteristic or information, to continuously vary the magnitude of the output of the device in proportion to the change or deviation detected by the probe to actuate at least one motor to correct or change the position of the probe and the slave.
Claims8
A probe or master for guiding a slave or associated apparatus along a path, said probe comprising a housing, a shaft extending longitudinally in said housing, a sensing tip carried on said shaft and adapted to engage said path and to detect vertical and horizontal changes and deviations therein, pivot means supporting said shaft, intermediate its length for pivoting about two axes at right angles to each other, and means supported by said housing and shaft, and having relative motion between portions thereof supported on said housing and shaft, respectively, for providing an electrical characteristic output in proportion to the magnitude and direction, both vertical and horizontal, respectively, of the change or deviation in said path detected by said sensing tip.
