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: A connecting piece includes a stamped metal sheet for conductively connecting poles of two batteries or battery cells, which connecting piece has a main body with a recess, wherein at least one insert element is arranged in the inner region of at least one recess. Either the insert elements have a groove on the circumferential face thereof, said groove running at least in regions of the circumference, or the main body has a groove on the inner face of the at least one recess therein, said groove running at least in regions of the circumference. The respectively corresponding component has a projection which is generated by material displacement when the two or one of the two components are/is pressed and which engages in the groove in an interlocking manner, so that the main body and each insert element are connected to one another, in an interlocking manner at least in regions, along the circumference of the insert element.
