Welding also represents the history of sheet metal shops. Even before AICHI METAL began performing various special surface treatments as we do today, welding was always a part of our factory. Today, AICHI METAL's welding technology itself has become "invisible" as we have arrived at ingenious ways to make it invisible from the surface. Still, we believe that the beauty of the joints is the beauty of a company's technology, and we are committed to the beauty of the invisible.
