Spot welding of metal sheets with vaccines

The present invention relates to a method for spot welding of two metal sheets, galvanized steels are mainly formed from, the includes the steps of : previously determining the arrangement area of the two mutually contacted plates, in which a welding spot is to be formed; forming a small hole in the center of the placement area at least one of the two sheets; introducing seed particles in the hole; spot welding of the two sheets by passing an electric current through the sheets by means of a pair of electrodes, wherein the particles comprise at least one material, which is selected from the group consisting of : carbon (alpha) + Ti-B alloy; (b is) Al-Ti B Re alloy + c is.
