By creating materials with suitable shapes and properties for the desired components, we achieve cost reduction through the joining of materials with gaps, joining dissimilar metals, and hollowing out parts. Toho Giken Co., Ltd.'s friction stir welding offers an overwhelmingly strong joining capability compared to other joining techniques like brazing and welding, allowing for machining after joining. We can produce cylindrical materials with steps, such as large-diameter and small-diameter materials, and by friction welding disks and pipes, we can create hollow-structured materials. 【Features】 ■ Capable of joining dissimilar metals such as iron and SUS ■ No need for molds, enabling cost reduction even for small lots ■ The greater the difference in gaps (steps), the better the cost performance *For more details, please download the PDF or contact us.

Toho Giken Co., Ltd.'s friction welding technology is a type of metal joining technique that uses the heat generated by friction between two workpieces to bring the joint area to a red-hot softened state, while simultaneously applying high pressure to achieve a completely oxidation-free bond at the atomic level. Using a technique called rotary friction welding, one of the materials (workpieces) to be joined is rotated at high speed while being brought into contact with the other. This utilizes the frictional heat generated at the contact surface to soften it to a red-hot state, and the joining is completed by applying further high pressure. Since the joint area is completely bonded over its entire surface, it achieves a strength equal to or greater than that of the base material. In destructive testing, whether pulled, bent, or twisted, the areas outside the joint fail first, resulting in a very strong bond. **Features** - Exceptional bonding strength compared to joining techniques such as brazing and welding - Machining is possible after joining - Capable of creating cylindrical materials with steps, such as large-diameter and small-diameter materials - Hollow structures can be created by pressure welding discs and pipes *For more details, please download the PDF or contact us.*
