Abstract
Method of laser welding which comprises at least two steps: a first step wherein the laser ( ) is operated for some time T at low intensity in order to create a melt ( ) in one part ( ) with little or no evaporation of matter, thereby reducing product contamination, and a further step wherein the laser is operated for a shorter time T at high intensity in order to push said melt ( ) towards a further part ( ), 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 (T ) in which the weld is post-heated.
