FIGURE 1. Schematic representation of the welding experiment where the laser is focused at the interface between the top and bottom materials and is raster-scanned to weld a large area. A lateral-view infrared (IR) image of a welded spot showing how the produced modification crosses the interface (left) and an IR image of a welded area consisting of a serpentine shape (right) are shown.
