We specialize in seam welding machines for special materials and thin sheets such as stainless steel, titanium, and 42 alloy. It all started when a certain steel manufacturer was able to produce 50-micron SUS foil, and a user remarked, "Cutting and bonding are part of working with metals!" during the steel manufacturer's material promotion. Since then, many special materials have been added, expanding the applications of this type of welding machine.
