Claim:
1. A method for laser welding first and second components, comprising: using a remote welding head that is in communication with a laser source, moving a laser beam across a portion of a surface of the first component at a scan speed sufficient to generate a series of protuberances along a laser-produced bead on the surface of the first component by means of a humping effect, wherein the laser beam does not melt an entire thickness of the first component along the laser-produced bead; juxtaposing said first and second components such that opposed surfaces of the first and second components are separated by protuberances of said series of protuberances on the surface of the first component; and laser welding said first and second components by scanning the laser beam, from the remote welding head and the laser source, in a region in which said surfaces are separated by said protuberances; controlling a height of the protuberances by controlling the scan speed of the laser beam; and wherein the scan speed is from 25 to 80 m/min.
