A welded component having mechanical properties in a welding seam region comparable or better to those in the non-influenced base material via a method including producing a hot-rolled steel product made of a high-strength air-hardenable steel with a material thickness of at least 1.5 mm having a chemical composition by mass in one embodiment of: C: 0.03 to 0.4; Mn: 1.0 to 4.0; Si: 0.09 to 2.0; Al: 0.02 to 2.0; P<=0.1; S<=0.1; N: 0.001 to 0.5; Ti: 0.01 to 0.2; Cr: 0.05 to 2.0; B: 0.001 to 0.1; Mo: 0.01 to 1.0; V: 0.01 to 0.2; optionally: Ni: 0.02 to 1.0; Nb: 0.01 to 0.1; and residual iron including conventional steel-accompanying elements, subsequently air hardening the produced hot-rolled steel product, then deforming the hot-rolled steel product in the air-hardened state to form a component, and producing welding connections using a fusion welding process on the component.

A metal member includes a first plate, and a second plate abutting against and welded to the first plate in at least one butt portion. In the butt portion, a length from a first end to a second end of a welding boundary line between the first plate and the second plate is longer than a length of a straight line connecting the first end to the second end of the welding boundary line.

Embodiments of systems and methods of additive manufacturing are disclosed. In one embodiment, a computer control apparatus accesses multiple planned build patterns corresponding to multiple build layers of a three-dimensional (3D) part to be additively manufactured. A metal deposition apparatus deposits metal material to form at least a portion of a build layer of the 3D part. The metal material is deposited as a beaded weave pattern, based on a planned path of a planned build pattern, under control of the computer control apparatus. A weave width, a weave frequency, and a weave dwell of the beaded weave pattern may be dynamically adjusted during deposition of the beaded weave pattern. The adjustments are under control of the computer control apparatus based on the planned build pattern, as a width of the build layer varies along a length dimension of the build layer.

A lap fillet weld joint and a lap fillet weld joint manufacturing method are provided. On a side of a first edge, a first metal plate is provided with a bulging portion that has an internal space of a prescribed size, and a second metal plate has a protruding portion that faces to the bulging portion and can be inserted into the bulging portion. In a state in which the protruding portion has been inserted into the bulging portion, the first metal plate and a second edge of the second metal plate are welded, and a first weld bead is formed.

Battery carrier for an electric motor vehicle, having a trough formed by a base and a peripheral frame coupled to the base, wherein the frame is formed from extruded hollow profiles and a cover is arranged on the frame. In the installation position, the frame has a web protruding in each case in relation to its upper side and/or lower side in such a manner that a defined gap with respect to the base and/or with respect to the cover is produced, with a sealant and/or adhesive being incorporated.
