| 5457301 | Capacitor discharge process for welding braided cable A capacitor discharge process for welding a braided cable formed from a plurality of individual cable strands to a solid metallic electrically conductive member comprises the steps of: (a) preparing the electrically conductive member for welding by bevell... | 10/10/1995 |
| 4991765 | Push rod manufacturing method A push rod is manufactured by projection-welding a bottom surface of an end element to a tapered annular end surface of a pipe. To prevent some inclination from arising between the bottom surface of the end element and the annular end surface of the pipe ... | 02/12/1991 |
| 4728768 | Percussion weld monitoring The quality of a percussion weld is sensed by measuring and analyzing certain features of the weld current signature. Instantaneous current is measured by a Hall sensor and permits isolation of the welder from the monitoring system. Weld quality is strong... | 03/01/1988 |
| 4700041 | Method and apparatus for projection welding Two metal plates 1a, 1b are projection welded together using a truncated conical projection 12 on a first one of the plates having a spherical end surface. The plates are pressed together through the projection, and a welding current pulse is applied whic... | 10/13/1987 |
| 4672164 | Composite metal matrix welding A method for joining individual pieces of material together includes the steps of heating the pieces to be welded together, at least one of which consists of a metal matrix with a relatively low melting point and a reinforcement material distributed there... | 06/09/1987 |
| 4417120 | Percussive arc welding A method and apparatus for improved percussive arc welding is disclosed. In this technique a test arc of a voltage no greater than the initiating voltage of the percussive arc welding is first applied across the pieces to be welded. The welding cycle is t... | 11/22/1983 |
| 4162388 | Apparatus and method for submerged percussion welding Submerged percussion welding is disclosed wherein the parts to be welded are in intimate contact with a liquid, such as water, during explosion and vaporization of the arc starter therebetween. In preferred form, one part is mounted to a stationary bottom... | 07/24/1979 |
| 3988563 | Welding method and means using foil electrode A welding method and means is disclosed utilizing a conductive foil disposed between or adjacent members to be welded together with the foil serving as one electrode and one or both of the members serving as another electrode of the welding circuit and wi... | 10/26/1976 |
