Abstract
A method for integrally bonding a cast aluminum component to a joining partner. The method includes laser-treating a region of the cast aluminum component that is to be connected to the joining partner. The laser treatment is carried out via a pulsed laser system having a pulse duration of 100 to 200 ns, and an impulse frequency of 10 to 80 kHz. The method also includes integrally bonding the cast aluminum component and the joining partner.

A method for integrally bonding a cast aluminum component to a joining partner, the method comprising:
- modifying a surface topology and surface tension of a region of the cast aluminum component that is to be connected to the joining partner using a laser-treatment, wherein
- the laser treatment is carried out via a pulsed laser system having a pulse duration of 100 to 200 ns, and an impulse frequency of 10 to 80 kHz,
- integrally bonding the cast aluminum component and the joining partner, and
- a content of aluminum in the cast aluminum component is 70% by mass in relation to the total weight of the cast aluminum component.
