This video shows components made from a sintering process, laser welded together:
The weld bead is 100 μm wide and 2 mm long. The welds were completed with minimal oxidation and minimal heat affected zone (HAZ) outside the area of interest.
As with all proper welds, this seam weld was stronger than the material itself.
