Abstract: An electrode in which the metallurgical structure of the active surface includes incoherent chromium precipitates, more than 90% of which have a surface of projection of less than 1 ?m2, the incoherent chromium precipitates having a size at least between 10 and 50 nm. The electrode further has a fibrous structure that is visible in a cross-section of the active surface of the electrode following surfacing and chemical etching. The fibrous structure includes a plurality of radial fibers having a thickness of less than 1 mm and of a substantially central fiberless region that has a diameter of less than 3 mm. The electrical conductivity of the electrode is greater than 85% IUPAC. The method for obtaining the electrode in a continuous casting process as well as to a use of the electrode in a resistive spot welding process.
