Definitions

  • the present invention relates to a method for connecting metal plates, and more particularly to a method for surface-connecting metal plates by means of exp osives- It is known that metal plates may be welded with each other by means of an explosive in that the explosive is placed on the one or both metal plates, which are to be welded with each other, in a uniform layer and is thereupon ignited. The two plates are so securely pressed against one another by the percussion jolt or detonation shock that they are welded with each other.
  • This prior art welding method is suited only for relatively small and/or thin plates; for with the attempt to apply this plating method industrially, it has been discovered that with large metal plates, for example, 2 x 5 In.
  • the explosive With a side ignition, the explosive is so arranged appropriately at the ignition side by an obliquely arranged metal plate that the shock wave after the ignition impinges on the upper plate in an obtuse angle.
  • the metal plate is thereby placed on the upper plate and is secured along the lateral supports consisting of wood or cardboard, for example, by adhesive strips.
  • the metal plate thereby flies to the rear during the detonation of the explosive.
  • the explosive that may be used may be either in plate, powder, or plastic form.
  • the height of the explosive layer and the slope angle depend on the used explosive, the size and the thickness of the plate and the metal to be plated. Spacing of the plates is also conditioned by the size thereof and the thickness thereof.
  • a method for surface-connecting superposed metal plates comprising the steps of placing the explosives on the upper metal plate in such a manner that the height of the layer of explosives decreases by about 50-70% from the ignition side over the extent of the plate and that the height of the layer of explosives is decreased along the sides adjacent the ignition side in stripshaped manner by only about 5 to 20%, and maintaining a predetermined spacing between said plates by securing metallic spacer supports to the lower plate only along the side opposite said ignition side.
  • An arrangement for the surface-connection of two metal plates by means of explosives which comprises an upper plate disposed above a lower plate, a layer of ex plosives positioned on the upper plate, the height of said layer decreasing from the place of ignition by about 50 to over the extent of the upper plate and the height of the layer of explosives decreasing by about 5 to 20% along the sides thereof adjacent the place of ignition.
