Abstract

The invention relates to a method for laser welding a first component to a second component, comprising:

placing the first component on the second component;applying a welding mask comprising a flat contact surface to the first component to press the first component onto the second component, the welding mask comprising a through-passage for a laser beam, defining a welding area on the first component, the contact surface at least partially surrounding said passage; emitting a laser beam by a head into the passage of the welding mask, to form a weld bead joining the first component to the second component in the welding area; wherein the welding mask is rigid and rigidly joined to the laser head and the focal length of the laser is constant, the constant focal length being ensured by the rigid mask.
