Abstract
Abstract A pulsed, optically pumped laser device is utilized to develop a beam of radiant energy which is concentrated and focused onto areas of juxtaposed articles to be joined. Conventionally, the radiant energy heats the areas of the articles to be joined so that the areas may be joined together. A highly concentrated magnetic field is developed by a magnetic device in the areas to be joined. The magnetic field induces a current in the articles placed in this field. The interaction between the high density field and the magnetic field produced by the induced current in the articles produces a force impulse on the articles and facilitates the application of a clamping force upon the articles during the period when the radiant energy of the laser is heating the areas of the articles to be joined. In cases where the articles are nonconductive, a conductive overlay may be utilized to provide the force transmission to the nonconductive articles beneath. Since high currents are required for a flashing lamp of the laser device and for the magnetic device, the system for joining the articles includes a single current supply source which supplies the same current simultaneously to the flashing lamp and to the magnetic device for effecting the simultaneous heating and clamping of the areas of the articles to be joined.
