Definitions
- the invention relates to the CMT technology (cold metal transfer) in which a filler wire of base material and Lotwerk ⁇ material for welding, in particular for repair is used.
- the object is achieved by a method according to claim 1.
- Figures 1 and 2 show the inventive method and the filler wire in a schematic representation.
- FIG. 1 shows a substrate 10, for example as a wall, which has a continuous crack 13.
- the invention is not limited to a wall.
- the substrate 10 or the wall preferably comprises a nickel- or cobalt-based alloy.
- the crack 13 is filled by a CMT-welding with welding mate rial ⁇ sixteenth
- FIG. 2 shows a cross section through a flux cored wire 1 representing the welding material 16 used in CMT technology.
- the cored wire 1 has a shell 4 made of a solder material, wherein within the shell 4, a filling 7 made of the solder ⁇ material and the base material of the substrate 10 is present.
- Solder material in this context means that the brazing filler material is at least 10K, 20K particular niedri ⁇ Gere melting temperature than the base material has a substrate of the 10th
- the proportion of the solder material in the filling 7 is Minim ⁇ least 10 wt .-%.
- Soldering material or significant distinctions means that compared with the base material at least one further alloy coins ⁇ approximately element exists or does not exist or the weight, volume, mol% - or at% interest differs by at least 10%, especially at least 20%.
- (+ CMT) is a soldering process after the deposit welding by heat treatment (+ T) quasi Runaway ⁇ leads, which allows a complete closing of the crack 13 through the entire wall thickness of the crack through.
