Abstract: The invention relates to a method for manufacturing at least a portion of a metal part of a turbine engine having a width L. The method is characterised in that said portion is manufactured by metal deposition using a MIG welding apparatus including a pulsed current generator and a pulsed deposition-wire flow, and used for varying said current and said flow, the manufacture being carried out in the form of metal beads (10) in several consecutive layers.

Abstract: The present invention relates to a method of brazing two materials (1, 2) together using a filler metal (3), which comprises the following steps: the filler metal is placed between the two contacting materials in a brazing zone where they are intended to be joined; on at least one of the two materials, which is mounted so as to move, a stress force is exerted along each of the directions of expansion provided for the two materials; the assembly in the brazing zone is brought to what is called a brazing temperature, which is both above the melting point of the filler metal and below the melting point of each of the two materials; during the temperature rise, the forces exerted on the materials to be assembled are gradually reduced as said materials expand, so that there is substantially no longer a force exerted on the materials when the brazing temperature is reached; and, once the filler metal has melted and wetted each material to be assembled, the assembly is cooled so as to solidify the filler metal, whic
