摘要
A method for laser welding first and second components is provided including moving a laser beam across a portion of a surface of the first component at a speed sufficient to generate protuberances on the surface of the first component by means of a humping effect, juxtaposing said first and second components such that opposed surfaces of the first and second components are separated by said protuberances on the surface of the first component, and laser welding said first and second components by scanning the laser beam in a region in which said surfaces are separated by said protuberances. The height of the protuberances can be controlled by controlling a scanning speed of the laser beam.
