An additive manufacturing system includes an energy source and a material delivery device. The energy source is configured to direct an energy beam toward a component to form a melt pool. The material delivery device is configured to feed a wire toward the melt pool to deposit material on the component. In some examples, the material delivery device is configured to discharge a current to the wire to disengage the wire from the melt pool. In some examples, the material delivery device is configured to measure an arc voltage between the wire and the component.

In a vehicle to which the present joining structure of vehicle steel plates is applied, a third welded portion is set between a first welded portion and a second welded portion, wherein at the first welded portion, a pillar outer rear flange, an SM outer rear flange, a pillar inner rear flange are joined to one another; and at the second welded portion, the pillar outer rear flange and the pillar inner rear flange are joined to each other. At the third welded portion, the pillar outer rear flange and the SM outer rear flange are joined to each other. Accordingly, a tensile load F acting on the pillar outer rear flange is distributed toward the SM outer rear flange side.

Techniques and devices are disclosed for fabrication workstation and assembly layout device. The fabrication workstation includes a table with a work surface. The work surface being a continuous surface and configured to support a plurality of components for fabrication of an assembly, such as an assembly of metal components. The device further includes a beam located above the work surface. The beam is operatively coupled to the table, such that the beam moves relative to the work surface in a first direction. A marking device on the beam is configured to move along the beam in a second direction different from the first direction. The marking device is further configured to mark the work surface in the shape of an assembly pattern. Assembly components are positioned on the assembly pattern to be assembled.

A hybrid bumper assembly for a vehicle includes a steel reinforcement beam and aluminum crush cans attached to end portions of the steel reinforcement beam. The reinforcement beam has a multi-tubular shape that is formed by a high-strength steel sheet that is roll formed to provide at least two tubular portions. A crush can has an interfacing portion that is coupled to an end portion of the reinforcement beam. The end portions of the reinforcement beam and the interfacing portion of the crush cans may be configured to attach together using a select joining technology in a manner that minimizes or eliminates bimetallic or galvanic corrosion between the reinforcement beam and the crush cans.

A junction structure includes a first metallic material, a second material different in type from the first metallic material, and a welding wire as a third material similar to the first metallic material. The second material is stacked on the first material. The molten metal of the third metallic material is deposited by arc welding into the through part of the second material so as to form a flanged or tapered bead, so that the first and third metallic materials and the second material are fixed together.
