Abstract: An apparatus comprises a current source, first and second wheels through which a current from the current source selectively flows, and a source of gas, wherein the first and second wheels receive first and second pieces of metal having overlapping portions, force the first and second pieces of metal together at said overlapping portions. The current from the current source flows through the first and second wheels in the overlapping portions of the first and second pieces of metal, generating heat in said first and second pieces of metal sufficient to melt a coating on the first and second sheets of metal where the first and second sheets of metal contact and overlap. The source of gas comprises removes said melted coatings away from the overlapping portions of metal to clean the metal surfaces in preparation for movement to a weld station where the pieces of metal are resistive seam welded or laser lap seam welded. Preferably the source of gas supplies an inert gas to prevent reoxidation of the pieces between the apparatus and the weld station.

Abstract: Welding a first body (11) of a first metal which has been plated on one surface thereof with a layer (13) of a second metal comprises the step of vaporizing a portion of said layer. This is done by directing a first pulsed laser beam (17) at the layer (13), the first pulsed laser beam having a first relatively high peak power and a first relatively low pulse duration. The vaporizing results in exposure of a portion of the first body (11). Thereafter, part of the first body is melted by directing a second pulsed laser beam (20) at the exposed portion of the first body, said second pulsed laser beam having a second peak power smaller than the first peak power and a second pulse duration longer than said first pulse duration. By using the same laser (18) in a two-step process, first to vaporize a portion of the plating, such as gold plating on Kovar, and thereafter using the same laser for making the weld, one can avoid a microcracking problem in a manner that is quick, simple and convenient.

Abstract: A heterodyning interferometric monitoring apparatus for simultaneously measuring in situ and in real time the optical and physical thicknesses of a sample during a deposition process. A linearly polarized monochromatic light beam is passed through a frequency shifter which produces therefrom a dichromatic light beam having two orthogonally linearly polarized components at respective different frequencies. The dichromatic beam is applied to a modified Twyman-Greene interferometer, from which two heterodyne light beams emerge. The first of the two light beams is a combination of light at the first frequency reflected from the sample and light at the second frequency reflected from a reference plate, from which the physical thickness of the sample can be determined using a heterodyne signal detector. The second light beam is a combination of light at the first frequency passed through the sample and light at the second frequency passed through the reference plate, from which the optical thickness of the sample can be determined using another heterodyne signal detector.
