Title: A method of and apparatus for welding small metal parts
Inventor: FLETCHER HARRY WELSLEY
IPC: B23K11/26
Filed: 1962-07-13
Abstract: 1,015,463. Supply systems for resistance welders; charging and discharging condensers. CARRIER CORPORATION. July 13, 1962, No. 27095/62. Heading H2H. [Also in Division B3] Small metal wires or filaments are welded together by bringing them into contact, thereby causing energization of a relay which discharges a previouslycharged capacitor through the two wires to effect the weld. The capacitor 23 is charged through the normally-closed contact arm 29 of relay 30 from a circuit including the rectifier bridge 19<SP>1</SP>, voltage regulator 19 and transformer 17 whose primary is controlled by one contact 15 of a switch 9. The Figure relates to the welding of a tap wire 63 to a turn 62 on the resistance wire of a potentiometer. The tape wire 63 supported by a tweezer, is brought into contact with the appropriate turn 62 to complete a circuit including a 6 - volt battery 35 and resistances 38, 41; 42, 42<SP>1</SP>. The resultant low current is used, together with transistors 45, 52, to produce a current sufficient to energize the coil 60 of relay 30 and to charge a capacitor 47, through a circuit including contact arm 50 of the relay 30. Operation of this relay opens contacts 50, 59, 29, movement of the last two completing a circuit including the tap wire 63 and turn 62, variable resistances 38, 61 and capacitor 23 which discharges to produce the weld. Resetting of the relay 30 is delayed by the discharge through coil 60 of the capacitor 47 which is shunted by a rectifier 48. The charging potential applied to capacitor 23 is determined by the size of the wires to be welded, and engagement of the tap wire 63 with the potentiometer turn 62 is effected with the aid of a microscope. The location of the turn is achieved by use of a test circuit prior to the welding operation, which circuit is controlled by the other contact 10 of the switch 9 and which contains a meter 13 to record the resistance detected by a probe 14 as it engages the various potentiometer turn, until that giving the lowest resistance value is determined. The resistances 38, 61 minimize the effects of a variance in the positioning of the weld on the turn. The Specification also refers to a known welding technique in which the tap wire is threaded through a glass tube having a small diameter bore and a bevelled edge which engages the turn at the point where the weld is to be formed, the other end of the wire being bent over the outer surface of the tube for engagement by a biased conductor connected to the capacitor.
