Welding method having a magnetic welding clamping device
View Patent ↗A method is provided in which two parts ( 2, 3 ) are connected to each other by a weld. The two parts ( 2, 3 ) are fixed by a magnet ( 4 ) during welding. A magnetic field of the magnet ( 4 ) influences the flow of a melt in the weld ( 6 ).
1. A method for connecting two components to each other during a welding operation by means of a weld seam, the method comprising the steps of:
fixing the two components with a magnet during the welding operation, the magnet being provided by a clamping device which presses the components together in an extensive manner, wherein by using the magnet, a gap with a constant width is produced between the two components; and
influencing, with a magnetic field of the magnet, the flow of melt in the weld seam.
2. The method as claimed in claim 1 , wherein the flow homogenizes the melt.
3. The method as claimed in claim 2 , wherein the magnetic field is changed during the welding operation.
4. The method as claimed in claim 2 , wherein a portion of the clamping device is provided on a first side of one of the components and another portion of the clamping device is provided on a first side of another one of the components, wherein a second side of the one of the components and a second side of the another one of the components define the gap, the second side of the one of the components being opposite the first side of the one of the components, the second side of the another one of the components being located opposite the first side of the another one of the components.
5. The method as claimed in claim 2 , wherein the magnetic field extends over the entire length of the weld seam.
6. The method as claimed in claim 2 , wherein an influence of the magnetic field on the melt is interrupted only when the melt has hardened sufficiently.
7. The method as claimed in claim 1 , wherein the magnetic field is changed during the welding operation.
8. The method as claimed in claim 7 , wherein a portion of the clamping device is provided on a first side of one of the components and another portion of the clamping device is provided on a first side of another one of the components, wherein a second side of the one of the components and a second side of the another one of the components define the gap, the second side of the one of the components being opposite the first side of the one of the components, the second side of the another one of the components being located opposite the first side of the another one of the components.
9. The method as claimed in claim 7 , wherein the magnetic field extends over the entire length of the weld seam.
10. The method as claimed in claim 7 , wherein an influence of the magnetic field on the melt is interrupted only when the melt has hardened sufficiently.
11. The method as claimed in claim 1 , wherein a portion of the clamping device is provided on a first side of one of the components and another portion of the clamping device is provided on a first side of another one of the components, wherein a second side of the one of the components and a second side of the another one of the components define the gap, the second side of the one of the components being opposite the first side of the one of the components, the second side of the another one of the components being located opposite the first side of the another one of the components.
12. The method as claimed in claim 11 , wherein the magnetic field extends over the entire length of the weld seam.
13. The method as claimed in claim 11 , wherein an influence of the magnetic field on the melt is interrupted only when the melt has hardened sufficiently.
14. The method as claimed in claim 1 , wherein the magnetic field extends over the entire length of the weld seam.
15. The method as claimed in claim 14 , wherein an influence of the magnetic field on the melt is interrupted only when the melt has hardened sufficiently.
16. The method as claimed in claim 1 , wherein an influence of the magnetic field on the melt is interrupted only when the melt has hardened sufficiently.
17. A welding method comprising:
providing two components that are to be connected to each other;
providing a clamping device comprising a magnet, said magnet producing a magnetic force;
pressing said components with a pressing force via said clamping device such that a gap with a constant width is produced between the two components, wherein the two components are fixed relative to each other via at least said magnetic force to maintain the constant width of said gap between the two components;
influencing a flow of melt in a weld seam of the fixed two components with a magnetic field of the magnet.
18. The method as claimed in claim 17 , wherein:
the magnetic field is changed during the welding operation; and
an influence of the magnetic field on the melt is interrupted only when the melt has hardened sufficiently.
19. The method as claimed in claim 17 , wherein a portion of the clamping device is provided on a first side of one of the components and another portion of the clamping device is provided on a first side of another one of the components, wherein a second side of the one of the components and a second side of the another one of the components define the gap, the second side of the one of the components being opposite the first side of the one of the components, the second side of the another one of the components being located opposite the first side of the another one of the components.
20. The method as claimed in claim 17 , wherein the magnetic field extends over the entire length of the weld seam.
