Definitions

  • the invention relates to a method for the non-detachable joining of components made of heat-fusible, metallic material, with a robot-guided welding unit for performing a hybrid welding process.
  • the invention also relates to an apparatus for carrying out the method specified above.
  • Methods and devices of the type mentioned above find, inter alia, industrial application in the joining of thick sheet metal, as it is used in particular in shipbuilding.
  • Submerged powder method has the disadvantage that there is a risk of shifting the midrib defect in the root area of the hybrid seam. This may mean that also the root of the already reworked by the sub-powder method weld must also be rewelded. This requires further work steps, namely, the already welded piece must be turned and the seam again, now on its other side, welded.
  • the submerged powder method used for rewelding also has the disadvantage that the heat input into the thick sheet and thus its distortion is not insignificant.
  • the invention has for its object to avoid the risk of cracking, that is, the formation of Friedrichrippende vomen, the hybrid welding of thick sheets.
  • a robot-controlled welding unit is used for carrying out a hybrid welding process.
  • a metal active gas high power welding process (MAG-HL) is performed at a predetermined distance following the hybrid welding process.
  • a hybrid welding process can be any combination of different welding processes.
  • Hybrid welding process and subsequent MAG-HL welding process are therefore carried out at the same welding speed along a seam, so that the inventive method can also be referred to as a "tandem welding process".
  • the involved in the execution of the hybrid welding process MSG burner is arranged on the welding unit aligned so that it is sluggishly inclined in the welding direction.
  • MAG-HL metal-active-gas-high-power welding process
  • Hybrid method filled the bottom 8 mm of the joint and the downstream MAG-H L process fills the rest of the joint with a filler wire of 1, 6 mm diameter.
  • a filler wire 1, 6 mm diameter.
  • a corresponding high-performance welding device is to be used.
  • the method of joining components made of heat-fusible metallic materials with a robot-guided welding unit comprises the hybrid welding process, namely a metal shielding gas welding process (MSG) in combination with a
  • Laser welding process performs.
  • This welding unit is coupled to a structural unit for carrying out a metal-active gas high-power welding process (MAG-HL) following the hybrid welding process. If the welding unit is guided along the seam to be welded between the thick sheets to be joined to one another, the assembly coupled thereto with the MAG-HL burner also travels at a predetermined distance from the welding unit.
  • MAG-HL metal-active gas high-power welding process
  • the guided by a robot welding unit can be provided with a support on which the assembly can be easily assemble, which carries the MAG HL welding torch.
  • the assembly may include a carrier which is mounted on the welding unit.
  • the carrier is advantageously designed so that can be adjusted in terms of their distance and their orientation to the welding direction, or the burner held thereon.
  • the drawing shows a schematic side view of an apparatus for carrying out the welding process.
  • the device for the permanent connection of components here a thick sheet 1 for shipbuilding made of heat-meltable, metallic material, has a robot-controlled welding unit 2. If the robot-controlled welding unit is guided in the welding direction according to the arrow VS, it thereby moves a burner 3 arranged on the welding unit, with which
  • Inert gas welding process is made.
  • a laser beam guiding component 4 which is likewise located on the welding unit, is moved along, so that the welding unit 2 ultimately carries out a hybrid welding process during movements along the thick sheet 1 at a predetermined speed in the direction of the arrow VS.
  • a carrier 6 With a screwing schematically indicated here by the hexagonal head 5, a carrier 6 is mounted on the welding unit 2.
  • the support carries a structural unit 7, on which a burner 8 is held for carrying out a metal active gas high-power welding process (MAG-HL).

  • the MSG burner 3 is sluggish, with respect to the welding direction VS.
  • the MAG-HL burner 8 also with respect to the welding direction VS, aligned sharply.

Abstract

L'invention concerne un procédé pour l'assemblage permanent de pièces en matériau métallique thermofusible à l'aide d'une unité de soudage conduite par robot pour l'exécution d'un soudage hybride. Selon ce procédé, un soudage à l'arc en atmosphère active à rendement élevé est effectué à une distance définie à la suite du soudage hybride. A cet effet, un module exécutant ce soudage à l'arc en atmosphère active à rendement élevé est entraîné par l'unité de soudage conduite par robot pour l'exécution du soudage hybride, le brûleur de soudage en atmosphère inerte utilisé pour l'exécution du soudage hybride étant traîné par l'unité de soudage.
