    摘要: The shielding gas mixture for the TIG or GTAW arc welding of stainless steels, in particular of duplex or super duplex steels, comprises, in argon, from 3 to 18%, advantageously approximately 10%, of helium and from 1 to 3%, advantageously approximately 2%, of nitrogen. This gas mixture makes it possible to ensure good corrosion resistance of the metal deposited, acceptable solidity of the welds and excellent arc stability, as well as a suitable viscosity of the molten metal appropriate to manual welding in all positions.

    摘要: A method and a system for diagnosing and/or solving, in particular remotely, a given technical problem likely to arise before, during or after a heat treatment operation on metals, in particular in the welding or cutting field, and to provide the most suitable solution thereto, and to do so by minimizing the time needed to solve this problem and therefore by reducing the loss of productivity likely to occur because of this technical problem.
