Abstract: The invention relates to an electrolytic cell (1) intended for production of aluminium including at least one collector bar (6) made of first metal and at least one complementary bar (20, 20') made of a second metal having an electrical conductivity greater than the first metal and arranged adjacent to one of the side faces of the collector bar (6) so that the external end (202, 202') of the complementary bar (20, 20') is at a specified distance A, A' from a specified end face (51, 51') of the block (5). The second end (202, 202') preferably terminates so as to limit heat losses from said cell (1). The invention makes it possible to obtain significantly lower voltage drops than known cells while avoiding excessive heat losses through the collector bars.

Abstract: A process is described for forming a structure of aluminum sheet components by spot welding the aluminum sheet components. In the process, aluminum sheet components are pretreated in a single step to both clean and increase the surface resistivity thereof by contacting the aluminum sheets with a pretreatment solution comprising a blend of sulphuric acid and phosphoric acid to clean the surface and generate a surface coating acting as a barrier film to increase the surface resistivity of the sheets. Thereafter the sheet components are secured together by spot welding.
