Abstract: in a method for producing a solder deposit in a metal sheet, a depression is made in a topside of the metal sheet through deep drawing, thereby causing material to protrude on a bottom side of the metal sheet. The metal sheet is then subjected to a material forming process to produce a collar such that the collar projects in relation to the topside. The collar is then at least partially pressed in a direction of the depression to reduce a cross-sectional area of a mouth of the depression, and the protruding material on the bottom side is completely pushed back so that the bottom side in a region of the depression is in one plane with neighboring regions of the bottom side.

Abstract: Spiral forming methods can be used to join edges of a rolled material along a spiral joint to form conical and/or cylindrical structures. Alignment of the edges of the rolled material can be controlled in a wrapping direction as the material is being joined along the spiral joint to form the structure. By controlling alignment of the edges of the material as the edges of the material are being joined, small corrections can be made over the course of forming the structure facilitating control over geometric tolerances of the resulting spiral formed structure.
