Abstract
A method for welding two components is provided. The method includes providing a first component, which has a convex elevation, and providing a second component, which has a through-hole. The method also includes placing the two components one against the other such that the convex elevation of the first component protrudes into the through-hole in an interlocking manner, and welding the two components along the rim of the through-hole by way of a laser welding device. The welding is performed without the use of a welding filler and the laser welding device is repeatedly switched on and off in a pulsed manner during the welding of the two components along the rim of the through-hole.
Claims18
A method for welding two components, the method comprising the acts of:
- providing a first component, which has a convex elevation;
- providing a second component, which has a through-hole;
- placing the first and second components on each other such that the convex elevation of the first component protrudes into the through-hole in an interlocking manner;
- in a first welding act, welding the first and second components along an edge of the through-hole by a pulsed laser beam and fixing the first and second components relative to each other by the first welding act, wherein the welding is performed without use of a welding filler material;
- and
- in a second welding act subsequent to the first welding act, fixedly connecting the first and second components to each other by the second welding act, wherein the second welding act comprises spot-welding the first and second components to each other at a plurality of locations spaced apart from the through-hole and/or welding the first and second components to each other via a weld seam at a location spaced apart from the through-hole and wherein a higher admission of heat is used in the second welding act than in the first welding act.
