Abstract (en)
[origin: CA3087845A1] The invention relates to an electrode for welding sheets of steel or aluminium, with a conductivity greater than or equal to 90% IACS and made of an alloy consisting, by weight based on the total weight of the alloy, of chromium in a proportion higher than or equal to 0.1% and lower than 0.4%, between 0.02 and 0.04% of zirconium, lower than 0.015% of phosphorus, the remainder being copper and less than 0.1% of unavoidable impurities, the electrode structure advantageously comprising incoherent chromium precipitates, more than 90% of which have a projected surface area of less than 1 um2, the precipitates having a size of between 10 and 50 nm, the electrode having a fibre structure consisting of radial fibres having a thickness of less than 1 mm and a substantially central fibreless region that has a diameter of less than 5 mm. The invention also relates to a method for producing the electrode.
