  • Method of laser welding
    Patent number: 6576864
    Abstract: Method of laser welding which comprises at least two steps: a first step wherein the laser (10) is operated for some time T1 at low intensity in order to create a melt (31) in one part (12) with little or no evaporation of matter, thereby reducing product contamination, and a further step wherein the laser is operated for a shorter time T2 at high intensity in order to push said melt (31) towards a further part (13), whereby large gaps between said parts can be bridged, yet further reducing product contamination thanks to the low laser energy needed to proceed with the further step. Optionally, a third step is performed during a third period of time (T3) in which the weld is post-heated.
    Type: Grant
