A device for reducing a stress concentration at an edge of a laminated composite material has an optical element, an actuator element, and a receptacle space for a first component of a laminated composite material which can be or is connected to a second component via a contact face and has an edge element above the contact face. The optical element defines a focus face for laser radiation for vaporizing laminated composite material. The actuator element is designed to move the optical element around a first component arranged in the receptacle space. and orients the optical element in such a way that an angle, including the first component, between the contact face and the focus face is smaller than 90. The angle is selected such that after vaporization of the laminated composite material at the focus face the stress concentration at the edge element is reduced under load.

Some embodiments of the present disclosure relate to an additively manufactured transport structure. The transport structure includes cavities into which components that use an external interface are inserted. A plurality of components are assembled and integrated into the vehicle. In an embodiment, the components and frame are modular, enabling reparability and replacement of single parts in the event of isolated failures.

The invention provides manufacturing a partially reinforced press formed product with high corrosion resistance and weldability. First and second steel plates having aluminum-based plating films are heated to an austenite range temperature by first and second furnaces, respectively, to transform the bodies of the first and second steel plates into austenite and form FeAl alloy layers on the surfaces of the first and second steel plates. Hot press forming is then performed to the first and second steel plates formed with the FeAl alloy layers, the first and second steel plates being superposed. The first and second steel plates, which are hot press formed, are then welded.

A planting implement including a first hollow support frame member having a first end and a first end plate connected to the first end. The first end plate has a first hole disposed therein. The planting implement also includes a second hollow support frame member configured for coupling to the first hollow support frame member. The second hollow support frame member has a second end and a second end plate connected to the second end. The second end plate has a second hole disposed therein. The planting implement further includes at least one spacer and at least one seal having an aperture. The at least one seal is configured to seal a connection between the first hollow support frame member and the second hollow support frame member such that a pneumatic pathway is established between the first hollow support frame member and the second hollow support frame member.

A sub-frame assembly supports a pair of wheels on a vehicle. The base may be an extrusion having a matrix of panels extending in a vertical direction. The sub-frame assembly has control arm brackets disposed on opposing ends of the base and attachment towers extending above the brackets providing attachment points to connect portions of an independent suspension to the vehicle and support a pair of wheels. The base, control brackets and attachment towers may be individual modular pieces. Left and right hand control brackets and attachment towers may be provided by respective unitary support pieces attached to opposing ends of the base. The unitary support pieces may be extrusions having panels extending in a transverse direction, nonaxial to the base. The base, control arm brackets and attachment towers, alternatively, may be provided by a single unitary extrusion having a matrix of panels extending in a transverse direction.

A bus bar includes a metal plate material. A plate face of the metal plate material includes a recessed portion. An inner wall of the recessed portion includes a first light-receiving face that is inclined relative to the plate face so as to receive a laser light beam L1 extending in a direction perpendicular to the plate face, and a second light-receiving face for receiving the laser light beam L1 that has reflected off the first light-receiving face.

A lap-fillet arc welding joint includes a weld bead, the weld bead being formed on an end portion of one sheet of overlapped two sheets and a surface of other sheet along the end portion. The other sheet includes a projecting portion projecting from the surface at a side of a weld toe of at least one of a start portion and a termination portion of the weld bead. The weld toe is located on a slope surface portion of the projecting portion at a side of the end portion of the one sheet.

A spark absorbing system for use with a cutting torch, comprises a cap having at least one spark opening therethrough and a spark capture unit coupled to the cap and positioned to capture sparks passing through the spark opening. The spark capture unit may comprise a tube extending from the cap and may include an outlet and a flow-reduction element positioned between the cap and the outlet and/or a spark accumulator between the cap and the spark capture unit. The flow-reduction element may comprise at least one baffle, screen or mesh. The spark absorbing system may further include a spark ramp extending from the cap opposite the spark capture unit and/or a shield, which may define a cutting space between the shield and the cap.

A weld joint assembly is provided. The weld joint assembly includes a first structural member having a first thickness. The weld joint assembly also includes a second structural member having a second thickness. The first thickness is different from the second thickness. The second structural member is connected to the first structural member through a weld joint. A plate is connected to the first and second structural members through the weld joint. The plate has a third thickness. The plate extends and abuts a surface of one of the first and second structural members and is welded thereto at outer edges of the plate leading away from the weld joint. At least a portion of the outer edge of the plate that is opposite to the weld joint is free of attachment to the surface.
