Patent ID: 8613139

Claim:
A method for manufacturing at least a portion of width L and height H of a metal part of a turbine engine, comprising: manufacturing said portion by metal application using a MIG welding apparatus comprising a pulsed current generator and a pulsed filler-wire feed rate, with which the current and the feed rate are varied, the manufacture being carried out using metal beads in a plurality of successive layers, wherein on a first layer, a first bead is produced along a first main axis and with a determined first width, a second bead is subsequently produced along a second main axis and with a second determined width, while ensuring an overlap on the first bead, said overlap varying from ¼ to ½ of the width of the first bead, and the number of beads necessary for the surface covered by the beads to be greater than the width of said portion are produced, wherein on a second layer, a first bead is produced while centering its axis on the intersection of the first two beads of the first layer, a second bead is produced while ensuring an overlap on the first bead, said overlap varying from ¼ to ½ of the width of the first bead, and the number of beads necessary for the surface covered by the beads to be greater than the width of said portion are produced, and wherein a number of layers are manufactured so as to obtain the desired height H of said portion of the part.
