摘要： The present application describes a method (22) for welding two parts to each other, said two parts being made from steel having a high thermomechanical yield strength, said welding method (22) comprising a welding step (24) in which a weld bead is created inducing a heat-affected zone (HAZ) to appear. The method (22) also comprises a heat treatment step (28) comprising a heating step (281), during which at least one portion of the weld bead and the HAZ is gradually heated to a treatment temperature (T), then a holding step (282) in which the portion of the weld bead and the HAZ is kept at the treatment temperature (T), then a cooling step (283) in which the HAZ and the weld bead are gradually cooled and pass from the austenitic transformation end temperature to the martensitic transformation end temperature of the steel of the parts in a time (T8/5) comprised between 7.5 s and 8.5 s, and pass from the austenitic transformation end temperature to the martensitic transformation end temperature in a time (T8/4) shorter than 15.5 s. The present application also describes a penstock obtained with such a method.

摘要： The present invention relates to a hydraulic installation where sediment concentration in the water flow circulating through the cited installation is monitored continuously. According to the invention, the hydraulic installation comprises a pressure-reducing device and a primary sensor: the pressure reducing device decreases the pressure and discharge of upstream water flow, comprising sediments, allowing that the primary sensor can operate continuously measuring sediment concentration from the upstream water flow. The hydraulic installation also comprises a calibrating device, providing the primary sensor with a reference value to be used for comparison matters and for establishing the content of sediment in the water flow.
