Abstract: A bonding head for connecting the electrically conductive leads of a tape cable or the like to other electrical conductors. The bonding head, which applies heat and pressure to the electrical conductors and leads to bond them together, is an elongated member comprised of a material having high mechanical strength but low thermal conductivity which contains a conduit comprised of a material having low mechanical strength but high thermal conductivity. A heating element inserted in the conduit supplies heat to the conduit and bonding head. This arrangement provides a bonding head having a high mechanical strength and hence structural failure and deformation of the bonding head is reduced.

Abstract: A process and apparatus are provided for applying gold contacts to a metal member by engaging the end of a hard gold wire with the metal member, welding the end of the wire to the member, heating the gold wire to establish a difference in its temper along a boundary in the region of the weld, and breaking away the gold wire along the boundary in the region of the weld. The apparatus comprises a first welding electrode having opposing jaws for receiving a gold wire, the jaws are actuatibly disposed on a yoke member which is pivotally mounted in an opposing relationship with a second welding electrode. The jaws clamp the wire and urge its end against the metal member during electrical welding of the wire end to the member. The opposing jaws are then released and retracted a first distance along the gold wire and then reclamp the wire. The yoke completes its pivotal travel pulling on the wire. The wire is deformed along the temper boundary in the region of the weld and then broken.

The welding head mechanisms are supported by compound connection apparatus that defines three interrelated axes that are cooperatively related to enable an electrode support to which welding wire electrode is automatically fed to precisely follow a joint of compound configuration that is established between angularly related portions of the work piece. Additionally, the welding head mechanisms are movable both vertically and laterally to facilitate proper positioning thereof to the work piece being welded.

Abstract: Apparatus for welding parts, such as pipes, end to end by means of an electric arc which is caused to rotate along the adjacent edges of the pipes. Two separate magnetic fields are used to cause the arc to follow a spiral path along the edges so that pipes having a wall thickness greater than one quarter of an inch may be welded.

Abstract: The method and apparatus in accordance with the present invention achieve the same working effect as grooving, drilling, cutting, and the like on a metal work by blowing off, with the use of a non-combustible jet gas, the molten metal heated and made molten by an electric arc. The atmosphere at the operating location where the electric arc and the jet gas are provided, is formed by a fluid atmosphere produced by the discharge of a non-combustible liquid. As a result, matters and substance such as dust particles, carbon monoxide, and the like existing around the operating location and serving to deteriorate the operating environment, are adsorbed and taken up by the fluid atmosphere for decreasing the amount of such matters and substance which are released to the operating environment surrounding the fluid atmosphere.

Abstract: A process and device for cutting an electrically conductive workpiece. The workpiece is moved relative to an endless circulating electrode while an electrical voltage is applied to the electrode and the workpiece sufficient to form an arc therebetween for melting the material of the workpiece, which melted material is then carried away by the circulating electrode. The electrode may also oscillate in the direction of relative movement and/or the electrical voltage may be interrupted at certain times such as when the electrode is operable to carry away the melted workpiece material.

Abstract: Arc welding and overlaying, particularly with strip electrodes, and particularly for overlaying by the submerged arc welding process with strip electrodes, can be regulated as to the distribution of arc energy by using strip electrodes which are run through male and female gears so that the current input of the electrodes is adjusted as to uniformity across the width of the overlay path.

Each work holder comprises an upright pin adapted to receive on and about itself a coil spring and a base member. The base member takes the form of an electrically conductive electrode part. At a loading station, springs are deposited successively on the pins and the table is indexed to move the pins and springs to a stress relieving station. Prior to the stress relieving station, a rotary brush engages the springs and indexes them about their pins to bring an end surface of an end coil into engagement with a small vertical abutment on the base member. The base members have inclined seating surfaces for the side surfaces of the end coils of the springs.

Abstract: A capacitance discharge stud welding apparatus which comprises a housing. A coil is positioned in the housing and an armature is located within the coil and is movable between first and second positions relative to the coil. A stud chuck is provided for the purpose of holding a stud and is connected to the armature for movement therewith. A relatively light spring constantly urges the armature and the stud chuck toward the first position of the armature in the direction of a metal member to which a stud held by the chuck is to be welded. Engagement of the stud held by the chuck with a metal member causes the armature to move to the second position relative to the coil and against the urging of the light spring. An electrical welding current circuit is provided and electrical connection means connect the welding current circuit to the chuck and to a stud held thereby.
