Method for forming a laser-welded connection and composite component

A method for forming a laser-welded connection, in which a first joining partner (11;11a) and a second joining partner (12;

• 12a) are connected to each other by action of a laser beam (1) in a joining region (30, 30a), forming a weld seam (2), wherein the first joining partner (11;
• 11a) is made of a material which is transparent to laser radiation and the second joining partner (12;
• 12a) is made of a material which is absorbent to laser radiation, and wherein a receptacle (25;
• 25a;
• 25b) for a component (13;
• 13a;
• 13b;
• 14) which is separate from the joining partners (11;
• 11a;
• 12;
• 12a) is formed by the joining partners (11;
• 11a;
• 12;
• 12a), wherein the receptacle (25;
• 25a;
• 25b) is designed as a through-opening (26), wherein the separate component (13;
• 13a;
• 13b;
• 14) includes a sheath (24;
• 24a;
• 24b), which is absorbent to laser radiation, wherein the material of the sheath (24;
• 24a;
• 24b) is arranged in a functionally communicating manner with the first joining partner (11;
• 11a), and wherein the laser beam (1) acts upon the sheath (24;
• 24a;
• 24b) so that by means of heat transfer from the sheath (24;
• 24a;
• 24b) the material of the first joining partner (11;
• 11a) is melted and closes off the through-opening (26).
