HYBRID ARC/LASER-WELDING METHOD FOR ALUMINIZED STEEL PARTS USING GAMMAGENIC ELEMENTS AND A GAS CONTAINING LESS THAN 10 % OF NITROGEN OR OXYGEN |
摘要 |
The invention relates to a hybrid laser/arc-welding method using an electric arc and a laser beam that are combined together within a single welding melt to which molten metal is supplied by melting a filler wire, wherein the welding melt is provided on at least one steel part including an aluminum surface coating, and a protective gas is used, characterized in that the filler wire contains at least 3 wt % of one or more gammagenic elements, in particular the gammagenic elements selected from C, Mn, Ni and N, and the protective gas consists of helium and/or argon with the addition of at least 10 vol % of nitrogen or oxygen. The method of the invention is particularly suitable for welding end-welded flanks used in the field of manufacturing automobiles or for tube welding. |
