Abstract: A filler material improves the quality of a joint seam formed during thermal joining of two metallic structural components and includes a core and a coating that surrounds the core at least in sections Because the filler material comprises a coating on the core, the alloying material for the coating may be selected largely independently of any possibly limiting metallurgical requirements in relation to the base material for the core so that with the use of the heterogeneous filler material optimal joint seam characteristics of the joined structural components always result, largely irrespective of the materials composition of the core If an essentially H-shaped cross-sectional geometry of the filler material used, moreover, preliminary fixing or alignment of the structural components that are to be joined in a thermal joining process becomes possible.

Abstract: The invention relates to a remakeable connector arrangement (1), in particular for application in motor vehicles, for the connection of high-current contact elements (4, 5), in particular battery poles and clamps. At least one spring connector element (2) is arranged between a sleeved contact element (5) and a pin-shaped contact element (4) which may be introduced into the former and is embodied as a helical spring connected at the ends thereof to form a ring. A remakeable connector arrangement is thus achieved which guarantees a permanently improved contact between the both contact elements (4, 5) in a simple manner. The invention further relates to a corresponding spring connector element (2) and application possibilities thereof.
