Abstract
La présente invention se rapporte à un procédé de soudage à l'arc des aubes sur la couronne ou sur la contre-couronne de rotors de machines tournantes. La soudage des aubes 2 se fait à partir de l'extérieur à travers la couronne dans laquelle sont fraisées des rainures borgnes, 3. Les premières passes 4 de fixation sont exécutées à l'aide d'une électrode de tungstène 5 sans enrobage de métal d'apport et en atmosphère inerte 6. Les passes suivantes de remplissage sont exécutées par le même procédé mais avec un métal d'apport. Le procédé élimine les exigences de hauteur minimale requises pour le soudage par l'intérieur et il donne des cordons de soudure robustes et d'une meilleure qualité de surface. La présente invention est notamment applicable aux machines tournantes pour le refoulement des fluides.
