Definitions

  • the invention relates to a method for joining a modularly constructed hot gas component by means of welding and assembled component.
  • Components such as turbine guide vanes and blades made of nickel-based superalloys.
  • the shovel e.g. Blade, outer and inner platform made of 15 optimized materials.
  • the tip of a turbine blade is made of materials that are more resistant to oxidation and corrosion compared to the blade root or blade.
  • the separately manufactured segments must be metallurgically linked with each other using suitable manufacturing technologies.
  • a suitable manufacturing process is a combination of laser beam welding and high-temperature soldering.
  • the object is achieved by a method according to claim 1 and a component according to claim 5.
  • Figures 1, 2 show schematically the invention.
  • the various components of the hot gas components e.g. Blade, outer and inner platform made of optimized materials and suitable manufacturing processes, e.g. casting technology, selective laser melting.
  • the pins are individually preheated to 773k - 1073k. As a result, compressive stresses between the platform 10 and the airfoil 7 are achieved and the components 7, 10 cannot slide together during the later joining process.
  • the preheating is regulated to a constant value by means of an (eg optical) temperature measurement and preferably does not melt the solder 16.
  • Laser beam welding is carried out in particular with single-mode laser radiation in the preheated state, which results in a reduction in the susceptibility to hot cracking of the nickel-based superalloy and, in addition, no stitching is necessary as preparation for the welding process.
  • Figure 1 shows an exemplary component 1, which is composed of two or more parts 4, 7, 10 and which are to be joined together.
  • it is a guide vane, but can also represent a moving blade or generally a component in which two components are to be joined together.
  • this component 1 of a turbine guide vane has a blade 7 and a lower and upper blade platform 4, 10, which 4, 10 in the joining area (here, for example, the stump of the blade on the platform 4) are particularly flat.
  • the two outer solid platforms 4, 10 can be manufactured using conventional investment casting technology or an additive manufacturing process such as SLS or SLM. The same applies to the blade 7.
  • FIG. 2 shows in more detail how two components 7, 10 are joined together.
  • the airfoil 7 or the component 7 has at least one, in particular three pins 13 ', 13'',13''', which through corresponding openings 14 ', 14'',14''' in the second component 10, the outer blade shape 10 can be inserted or inserted.
  • Airfoil shape 10 a solder material, in particular a foil or solder material, which was applied by means of laser deposition welding, is present.
  • the two components 7, 10 are then inserted one into the other, the solder material 16 then being between them.
  • the pins 13 ', 13' ', 13' '' are heated to correspondingly high temperatures, in particular from 773K - 1073K, in order to create a tension between the pins 13 ', 13' ', 13' '' and the blade shape 10 to reach so that these are biased.
  • component 1 Thereafter, high-temperature soldering of component 1 takes place in an oven, which can accommodate several such components.
