"simpler, sustainable, scalable, energy efficiency, space savings... few seconds drying time (was several minutes) particularly useful in roll-to-roll... combines spray coating with laser-beam processing for corrosion protection coatings for bipolar plates, without energy-intensive vacuum process... double-beam welding/  forming tools repair speeding production, using 2 simultaneous welding laser beams reducing cycle time almost 50%... apply high-quality wear protection coatings using extreme high-speed laser cladding"
