Friction stir welding is a technology that uses heat generated by friction to join metals together. The strength of the joint is equal to or greater than that of the base material. Therefore, it is a joining method that allows for the use of high-durability metals only in necessary areas, contributing to overall cost reduction by completing parts using friction stir welding. 【Features】 ■ It is possible to supply complex-shaped parts by combining with forged products! ■ By friction stir welding metals of different diameters, expensive materials can be used only in necessary areas, while the other can be replaced with cheaper materials. ■ For products with shapes that are difficult to process as a single piece, dividing them into two parts and processing one part before friction stir welding makes processing easier. ■ By friction stir welding materials of different diameters, it is possible to reduce material and processing costs compared to machining from round bars. *For more details, please download the PDF or contact us directly.

Here are some examples of our company's "friction welding products." We manufacture "shafts" that combine processed parts and round bars weighing 2-3 kg, as well as those that combine forged parts and round bars weighing 8-33 kg. Additionally, we have "gears" weighing 3 kg that combine two forged parts, and "pipe fittings" that are approximately 2-4 m long. We can also join different metals, such as stainless steel and iron, in addition to iron and iron. 【Examples of Achievements】 ■ Shaft: 2-3 kg (processed part + round bar), 8-33 kg (forged part + round bar) ■ Gear: 3 kg (forged part + forged part) ■ Pipe fitting: approximately 2-4 m ■ Rod: 2-86 kg ■ Anchor bolt: 1.4 kg ■ Axle shaft *For more details, please refer to the PDF document or feel free to contact us.

The parts joined by friction stir welding are characterized by high strength and precision. By using frictional heat and high pressure, impurities at the joint surface are expelled, allowing the entire contact surface to be joined, resulting in a joint that is stronger than that achieved through welding. The tensile strength of the joint area processed by friction stir welding becomes stronger than that of the base material, and when a tensile test is conducted, the fracture occurs in the base material rather than at the joint.

We would like to introduce the work process of friction welding products at Edogawa Kanko Co., Ltd. First, the materials are cut, heated, forged, and then the processed products are received, followed by the execution of the friction welding work. After friction welding, the products undergo heat treatment, shot blasting, and inspection before shipment. 【Advantages】 ■ By performing friction welding on materials of different diameters, it is possible to reduce material and processing costs compared to machining from solid round bars. ■ If integral processing is difficult, dividing the material and performing friction welding makes processing easier. ■ Since different metals can be joined, it is possible to reduce costs by using high-priced materials only in the necessary parts. *For more details, please refer to the PDF materials or feel free to contact us.

By joining the blade section and the shaft section through friction welding, we have made the shaft section from inexpensive steel material, achieving a reduction in material costs. Unlike welding, this method allows for the joining of dissimilar metals while maintaining strength, making it suitable for components that require high strength. 【Product Specifications】 ■ Turbine Wheel Shaft 　● Material: INCONEL + SCM440 　● Size: Joint section Φ38 x Φ50

Friction stir welding is a technology that uses heat generated by friction to join metals together. The strength of the joint is equal to or greater than that of the base material. Our company introduced friction stir welding machines early on, enabling us to supply complex-shaped parts in combination with forged products. 【Advantages】 ■ By friction stir welding dissimilar diameter materials, we can reduce material and processing costs compared to machining from solid round bars. ■ For products with shapes that are difficult to process as a single piece, we can divide them into two parts, process one part, and then join them using friction stir welding, making processing easier. ■ By friction stir welding metals of different diameters, expensive materials can be used only where necessary, while cheaper materials can be substituted elsewhere. *For more details, please feel free to contact us.
