摘要：the invention relates to a method for welding parts (1, 2) so as to make thestainless steel by melting a filler metal at the junction of the parts (1, 2) and a bead (3)satisfying at least one dimensional test target, characterized in that it comprises\étap are as follows: (a) determination by means of data processing (11) of aplurality of vectors of values of at least one potentially acceptable welding procedureaccording to the physicochemical properties of the parts (1, 2) and \\/ or weld metal. (b)for each of these vectors, calculating a vector associated with the theoretical values of atleast one dimensional parameter of the weld bead (3) using a model of the molten bath.(c) estimated by kriegeage a function to express the dimensional parameters of the weldbead (3) on the basis of the operating parameters of welding. (d) determination ofoptimal values of operating parameters, for which the estimated values with the weldingparameters according to the size and the weld bead (3) satisfy the dimensional criteriatargets; (e) welding of parts (1, 2) by a welding device (4) is configured to apply theoptimum values of the welding and operating parameters determined.
