A sandwich structure employs a core sheet including alternating peaks and valleys therein, and at least one outer face sheet including grooves or ribs therein. In another aspect, a sandwich structure includes at least one core and at least one adhesively bonded outer face sheet including elongated grooves or ribs formed therein. Yet another aspect of a sandwich structure has raised ridges bridging between adjacent peaks in a core sheet in one direction but not in a perpendicular direction, which synergistically interface, engage or contact with grooves or ribs formed in an outer face sheet.

A frame for bonding a first glass component to a second glass component with a desired thickness of adhesive is disclosed. The frame has a horizontal top portion sized to overlap the top surface of the first glass component. The horizontal top portion has a distal surface which is configured to contain the adhesive when poured on the top surface of the first glass component. The horizontal top portion is thicker than the layer of adhesive to be used so that the second glass component may be placed within the frame to abut the distal surface. The frame also has a vertical side portion which extends downward from the horizontal top portion and is sized to wrap around the first perimeter.

To produce pretinned strips of connectors for PV cells, a metal foil (30) is guided through a roll gap (46) of a rolling mill in which at least one work roll (48) has a surface with a corrugated structure with the result that a corrugated structure which has crests or peaks and troughs is embossed into at least one side of the metal foil (30), soldering tin in the form of solder preforms (54) is applied to the side of the metal foil (30) with the embossed corrugated structure, wherein the soldering flux necessary for pretinning has been applied in advance to the solder preforms or the metal foil, the solder preforms (54) are connected to the metal foil (30) or applied to it and melted on and the pretinned metal foil (30) with the embossed corrugated structure is separated into parallel ribbons. The solder preforms (54) are sufficiently thick for the corrugated structure to be at least full after the solder preforms (54) have been melted on.

The invention relates to a method for producing a half-shell part with a drawing punch and a drawing die. The object of providing a method for the process-reliable and cost-effective production of highly dimensionally stable half-shell parts is achieved in that, in a single work step, the drawing punch is advanced into the drawing die, a sheet metal blank is preformed into a sheet metal raw part with at least one base section, at least one frame section and optionally a flange section, wherein during the preforming with the drawing punch a material excess is introduced either into the base section and the frame section or into the optional flange section of the sheet metal raw part, and the sheet metal raw part is finished to form a half-shell part and calibrated.

Disclosed herein is a method of making a structure by ultrasonic welding and superplastic forming. The method comprises assembling a plurality of workpieces comprising a first workpiece including a first material having superplastic characteristics; ultrasonically welding the first workpiece to a second workpiece, to form an assembly; heating the assembly to a temperature at which the first material having superplastic characteristics is capable of superplastic deformation, and injecting a fluid between the first workpiece and the second workpiece to form a cavity between the first workpiece and the second workpiece.

A hot-dip-coated, non-skin-passed, cold-rolled metal strip is provided. The metal strip is obtained by passing the metal strip through a bath of molten metal, wiping the coated metal strip with nozzles that spray a gas on each side of the strip and making the strip pass through a confinement zone. The metal coating of the metal strip includes a waviness Wa0.8 of less than or equal to 0.70 μm, 0.2 to 8% by weight of aluminum and magnesium in the following proportions: 0.1 to 8% by weight of magnesium for an aluminum content equal to or greater than 0.2% but less than 2% by weight or a content greater than 5% but less than or equal to 8% by weight of magnesium for an aluminum content equal to or greater than 2% but less than or equal to 8% by weight, and up to 0.3% by weight of additional elements, the balance being zinc and inevitable impurities. Metal parts are also provided.
