An apparatus (10) for joining a predetermined geometrical profile shape from a sheet material (SM) includes a positioning assembly (12) including a base member (14) and a frame (16) that is operable to receive the sheet material (SM), to configure the sheet material in a predetermined orientation and to linearly translate the sheet material along a process direction (20). A Z-bar (22) is configured to guide a first longitudinal edge (FE) and second longitudinal edge (SE) of the sheet material (SM) into adjacent alignment along the process direction (20). A welding and forging assembly (60) welds and then forges a seam between the first longitudinal edge (FE) and the second longitudinal edge (SE) of the associated sheet material (SM).

A method includes mounting a hollow cylinder on a turntable, positioning an additive-manufacturing deposition tool at a surface of the hollow cylinder, and rotating the hollow cylinder on the turntable while depositing material on the hollow cylinder with the deposition tool. Further, a method includes making an opening in a wall of the hollow cylinder, forming a part to fit in the opening, and welding the part to the hollow cylinder such that the part fills the opening. The hollow cylinder has an inner radius and an outer radius, and the part is formed with an inner radius of curvature and an outer radius of curvature substantially similar to the inner radius and outer radius, respectively, of the hollow cylinder when the part is positioned in the opening.

The invention relates to a method for producing a coil (6), in which, by means of casting, a semi-finished product (5) in the form of an elongate conductor is formed in a cavity (2) of a casting tool and the coil (6) is formed following a demolding of the semi-finished product (5) by shaping this semi-finished product (5), wherein the form of the semi-finished product (5) may be derived from a shape of the finished coil (6) by stretching along a longitudinal axis of the coil (6) and/or by bending this longitudinal axis, and wherein the semi-finished product (5), during the shaping, is bent and compressed so that windings of the coil (5) already present in the semi-finished product (5) are brought closer to one another at least in some regions during the shaping and are brought into an arrangement along the longitudinal axis of the finished coil (6), wherein the conductor, whilst being shaped, is twisted or bent by no more than a right angle over the course of each individual turn. The invention also relates to a coil (6) produced in this way and to a casting tool which may be used to carry out the described method.

The invention relates to a method for producing a helical metal body (Γ), in which initially a preformed, helical metal body is produced in a mould by a casting method and is subsequently compressed along its longitudinal axis by deformation.
