江戸川鍛工 Company Overview

By performing friction welding at necessary points such as shafts and gears, we achieve processing-free results! A metal joining technology that improves yield and contributes to cost reduction!

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.
