    Abstract: Method and apparatus are provided for welding studs to a work surface wherein a substantially smut free surface is produced adjacent the weld. Apparatus is provided for depositing a thin coating of liquid in spray form onto the work surface adjacent the area whereon the stud is to be welded, prior to the welding operation. Contaminates formed in suspension in the liquid during the welding operation are removed by removal of the liquid suspension which is accomplished in a simple and inexpensive manner.

    Abstract: Apparatus for use with stud welding equipment employing a stud welding gun, a power supply and a controller for initiating the welding cycle and controlling the discharge of welding energy from the power supply across the stud and workpiece which detects the occurrence of bad welds and operates to generate an alarm signal and/or discontinue further operation of the welding apparatus. A first circuit is employed across the welding power supply and senses the discharge thereof to generate a first signal indicative that a normal weld has occurred. A second circuit connected through the controller generates a second signal upon the weld command to the controller indicating an attempted weld. The first and second signals are fed into a binary counter wherein the first signal indicating a successful weld resets the counter to 0 and the second signal indicating the weld command advances the counter to a count of 1. Upon the occurrence of the first bad weld indicated by the absence of a first signal, the second signal will advance the binary counter to a binary count of 2 upon which a signal light will be turned on. Upon the second successive weld failure, the next appearing second signal indicating a second weld command will advance the binary counter to a count of 3 which functions through circuit relays to disable the welding apparatus from further operation. One bad weld followed by a normal weld will result in the first signal resetting the binary counter to 0 and permitting continued operation.
