Definitions

  • the electrical resistance being inversely proportional to the electrical conductivity, it is necessary, for welding aluminum, to have an electrode having an electrical conductivity greater than 90% IACS (for International Annealed Copper Standard), while a higher conductivity at 75% IACS is required for welding steel.
  • IACS International Annealed Copper Standard
  • the present invention relates to an electrode made of copper, chromium, zirconium and phosphor alloy for welding metal sheets made of steel and aluminum or aluminum alloys, characterized in that the alloy consists of chromium in a proportion greater than or equal to 0.1% and less than 0.4% by mass, of zirconium in a proportion of between 0.02 and 0.04% by mass, of phosphorus in a proportion of less than 0.015% in bulk, the remainder of the composition being copper and unavoidable impurities in a proportion of less than 0.1% by weight, and the electrical conductivity of said electrode being greater than or equal to 90% IACS (International Annealed Copper Standard).
  • IACS International Annealed Copper Standard
  • the cooling of said bar of step c) can be carried out at a cooling rate of at least 30 ° C./s for temperatures below 900 ° C., until the bar is cooled to a temperature at more than 100 ° C.
  • the diameter d of the continuous casting cylindrical die is less than 70 mm.
  • step c) of the process is particularly important, resulting in rapid solidification and extremely powerful peripheral cooling.
  • These cooling conditions which are furthermore applied to a cylindrical mold having a reduced diameter of between 20 and 70 mm, preferably between 20 and 40 mm, contribute to obtaining a bar with a columnar solidification texture orientated in such a way radial. This texture is visible by making a cross section of said bar, and on 1 'the entire volume of the latter.
  • chromium precipitates are at the origin of the improvement of the welding performance of the electrode, increasing the resistance of the latter to hot creep.
  • these precipitates have the function of delaying or blocking the diffusion of iron and zinc which are at the origin of the chemical corrosion of the active face of said electrode.
  • the% IACS conductivity was also measured for these two electrodes, before and after welding, and after 30 welding points for the electrode of the invention.
