The invention relates to a process for welding aluminium foils of different thickness and width, designed especially for making electric transformers. According to the invention, the process consists in serially spot welding some aluminium foils (1, 2) using a welding assembly comprising several electrode bundles (3, 4), each of them having nine squarely-arranged electrodes supplied by independent power supplies, each bundle being used for a predetermined period of time. The diameter of a contact electrode of the electrode bundle depends on the thickness of the foils to be welded.
