Title: Composite materials made by explosion welding
Inventor: LIESNER CHRISTIAN DR-ING
IPC: B23K20/08
Filed: 1974-12-12
Abstract: Process for mfg. a composite material, by using explosion welding to apply a cladding onto a carrier layer. A self-supporting plate of the cladding, e.g. Ta, 1 mm thick, is applied to the carrier layer, e.g. Cu, 10 mm thick in such a ratio that the desired thickness ratio, e.g. 1:10, is obtd. and then the composite material (Ta-Cu) is rolled out one or more times to obtain the desired thickness, e.g. 0.1 mm of Ta on 1 mm of Cu. The finished thin material (e.g. Ta-Cu) is pref. treated as a material consisting of a single layer and applied to a further carrier, e.g. a steel vessel, by explosion welding. The technique avoids the formation of defects such as fissures, folds, stress and distortion in explosion plated coatings.

Title: Copper surfaced building plumbing and sheet-metal work sheet - comprising centre ungalvanised sheet steel layer coated with soldered copper foil
Inventor: PFLAUM PETER
IPC: E04D3/16
Filed: 1975-02-28
Abstract: The purpose is to provide, at low cost, metal sheeting, for roof and rainwater guttering, drainpipes, roofing, sill cladding, other building constructions, tinsmithing, and plumbing uses, which is durable, rust and corrosion-resistant, and does not need to be painted, even where industrial gases are a hazard. This is achieved by the use of a load bearing centre layer of non-galvanised sheet steel, coated with a laminar-soldered sheet of copper foil on both sides, providing a sealed connection which completely protects the steel from atmospheric conditions. The sheet steel can be immersed in a tinning bath, and the prepared copper foil rolled straight onto it. This is much less expensive than copper sheeting of the same strength, with the same qualities.
