Problems solved by technology

Now research has found that due to the over 800×10 5 Extremely high pressures in the Pa range, under vibration loads, as in the case of internal combustion engines for vehicles, can lead to failure of the weld due to overloading in the case of currently used welded connections

Abstract

The invention relates to a component assembly, comprising a first component (10), a second component (20), and an optical fiber laser welding connection (2) disposed between the first component (10) and the second component (20), which can connect the first component to the second component at a bonding gap (6). The optical fiber laser welding connection (2) at least includes a first welding seam (3) and a second welding seam (4), which are arranged in parallel in a manner of mutually contacting. The invention also relates to a method for manufacturing the optical fiber laser welding connection.

Description

technical field [0001] The invention relates to a component assembly with a fiber optic laser welding connection, an injector, in particular a fuel injector with such a component assembly, and a method for producing a fiber optic laser welding connection. Background technique [0002] Various configurations of welded connections between two components are known from the prior art. For example, in the manufacture of fuel injectors, two components, namely the inner pole and the connection sleeve, are connected to one another by means of a welded connection. Here, a single weld seam is produced with the aid of a disk laser. As the environmental protection standards of internal combustion engines continue to increase, the injection pressure of diesel internal combustion engines and gasoline internal combustion engines is also continuously increasing. Now research has found that due to the over 800×10 5 Extremely high pressures in the Pa range, under vibration loads, as in the...
