MODE OF WELDING OF THE CURRENT FEEDS OF AN ALUMINUM ELECTROLYZER Russian patent published in 2008 - IPC B23K31/00 B22D19/04 C25C3/16 

FIELD: the invention may be used for connection of metallic details primarily of aluminum elements of the current feeding bus of electrolyzers.

SUBSTANCE: the aluminum is heated in a melting pot to 1100-1400^oC and delivered into a foundry form installed in the gap between the melting pot and the built-up surface of the metallic elements. The aluminum is fed through a slit channel with the square of the transversal section equal or larger then the tenth part of the square foundry form in the scheme. The channel is fulfilled in the bottom of the melting pot along the contour of conjugation of welded metallic elements. The height of the level of the melt of aluminum fed into the foundry form is chosen larger then the correlation of the total square of the built-up surface of the metallic elements in the foundry form to the inner perimeter of the foundry form in the scheme.

EFFECT: the mode provides reduction of losses of electric energy due to reducing electric resistance of welded connections at increasing their rigidity.
