The heat changes the optical properties of Clearweld, leaving behind a highly transparent seam (see Fig. 2). Transmission laser welding can be subdivided further according to the various means of ...

The production of fuel cells requires the use of a rapid laser welding process; however, welding at too high a speed results in humping, marked by surface irregularities on the weld seam. A team led ...

Through numerous sample runs, [Dries] found that defocusing the laser to a spot size of 1.5mm at low power settings makes for a perfect threadless seam. The resulting test pockets are quite ...
