Manufacturing of Steel Pipe Piles Using Friction Welding

Contributes to cost reduction through material and labor hour reduction. Suitable for mass production with stable joining quality and production system.

We propose the fabrication of steel pipe piles using friction stir welding. This method achieves "full-strength joints" where the strength of the joint surface does not fall below that of the base material due to solid-state diffusion bonding. It allows for rapid joining, significantly improving productivity. In some cases, processing time can be reduced by over 90% compared to complete fusion welding. Additionally, the joint area experiences minimal thermal impact, allowing for a reduction in processes. Since beveling and backing bars are unnecessary, this also leads to material savings, contributing to overall cost reduction. By managing parameters through machinery, we can consistently provide high-quality products that are not dependent on the skill level of welding operators. 【Features】 ■ The joint strength is "full-strength." ■ Productivity is significantly improved. ■ Joint quality is stable. ■ Products can be supplied with a stable production system. *For product details, please refer to the materials.
