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 reached a point where we have devised 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.
