TLDR
In this paper, a corrosion-resistant joint between metallic structural elements by spot welding is produced by pretreatment of the joining surfaces (4', 5') for spot-welding operation, and adhesive application of anti-corrosive layers (8), as well as degreasing, rinsing, pickling, and application of a layer (8) of sealing compound at least on one side of one of the structural elements.Abstract:
Method of producing a corrosion-resistant joint between metallic structural elements by spot welding, the method being characterised by the steps: - pretreatment of the joining surfaces (4', 5') for - the spot-welding operation, and - the adhesive application of anti-corrosive layers (8), as well as - degreasing, - rinsing - pickling, - application of a layer (8) of sealing compound at least on one side to the joining surfaces (4, 5) of one of the structural elements (4, 5), - tacking of the structural elements (4, 5), - spot-welding operation with - setting of a defined electrode pressure for obtaining metallically bright joining-surface sections in the area of the electrode pressure point (10), - current supply for producing the weld spot (11), and - hardening of the sealing compound (8).read more

Composite material made of two steel cover sheets resistance-welded together and an intermediate layer
TL;DR: In this paper, a composite material in band or slab form made of two cover plates ( 1, 2 ), made of steel, which can be resistance welded together via electrically conductive bodies ( 4 ), and an intermediate layer ( 3 ) made of a filler material in which the bodies are embedded, with the bodies being implemented as curved slugs, lying pressed flat between the cover plates.

Elastic sealant compositions and adhesive materials, and the use thereof
TL;DR: The use of UV absorbers, for example benzophenone or trioxazole derivatives, causes surprising improvements in adhesion of the compositions, which are preferably used as joint sealants as discussed by the authors.
