Abstract
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).
Claims20
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.
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.
