ULTRASONIC WELDING OF DISSIMILAR SHEET MATERIALS

A ultrasonic welding method of joining dissimilar-material workpieces, such as sheet materials, and the joined components formed thereby. The method includes applying ultrasonic energy to a thermoplastic piece to fill a hole of a dissimilar piece to form a weld point that is made up with polymer from the thermoplastic piece. In general, the geometry of the thermoplastic piece is not altered during the process. The dissimilar piece generally has a higher melting temperate and can be metal, thermoset polymers, or other thermoplastic material. The welded pieces can be arranged in a lap, laminate, or double lap configuration. In some embodiments, the hole of the dissimilar sheet material includes undercut features that improve the mechanical interlock between the dissimilar pieces. In some embodiments, the weld point has a mushroom cap to improve mechanical interlock.

Bonding methods for laminated light alloy parts

A method for the additive manufacturing of an object and a system for manufacturing an object. The method includes depositing a second foil sheet onto the first foil sheet, wherein the first foil sheet and the second foil sheet each comprise a structural layer, forming a layer stack comprising the first foil sheet and the second foil sheet, the layer stack comprising an object section and at least one support section configured to enclose the object section in the layer stack, and applying at least one of heat or pressure to opposite sides of the layer stack with a first plate and a second plate, wherein applying the at least one of heat or pressure increases he temperature of the layer stack to a temperature lower than the melting temperature of the structural layer, and the at least one of at or pressure bonds the first foil sheet to the second foil sheet in the layer stack, the first plate and the second plate are in contact with the at least one support section, and the at least one support section is configured to conduct the at least one of heat or pressure through the layer stack to the object section.

Mobile waterstop welding apparatus
09827706 · 2017-11-28 ·

A mobile waterstop welding apparatus includes a first and second support member for supporting a first and second waterstop section, respectively. The second support member is movable between a loading configuration, a heating configuration, and a welding configuration. In the loading configuration, the first and second support members are spaced apart so that the first and second waterstop sections may be loaded onto the first and second support members. In the heating configuration, the first and second support members are spaced apart so that a heating iron may be placed in-between respective welding ends of the first and second waterstop sections. In the welding configuration, the first and second support members are moved towards each other so as to weld the first and second waterstop sections together at their respective welding ends. During the welding process, a spring assembly may urge the first and second support members towards each other.
