Abstract: Stud welding apparatus including circuitry for effecting a hammering action of the stud against the workpiece to break through paint, scale, etc. to establish good electrical contact. The stud welding gun includes a lifting solenoid and the hammering is effected, in one species, by converting the solenoids normal full wave rectified input to half wave rectified output and in a second embodiment by interrupting the DC power supply to the gun solenoid through a solid state device by an associated frequency variable multivibrator. Hammering is discontinued upon the sensing of the establishment of welding current across the stud and workpiece in one species and in a second by continuing hammering until the electrical resistance across the stud and workpiece reduces to a predetermined level. A safety timer circuit is employed to discontinue hammering after a predetermined time irregardless of the establishment of acceptable electrical contact.

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.
