Customized CBN Friction Stir Welding Tool for Friction Stir Welding
Descrizione
Combined with top institutes and universities and introduced high-tech equipment, FUNIK has developed high quality polycrystalline cubic boron nitride (PCBN) FSW tools with a range of sizes for various applications.
FUNIK now is the first and only one manufacturer of PCBN FSW tools in China.
Friction stir welding(FSW) is a widely used solid state joining process for soft materials such as aluminium alloys because it avoids many of the commend problems of fusion welding. However, commercial feasibility of the FSW process for harder alloys such as steels and titanium alloys awaits the development of cost effective and durable tools which lead to structurally sound welds consistently.
Owning to high strength and hardness at elevated temperatures along with high temperature stability, PCBN is a preferred tool material for FSW of hard material welding. Furthermore, the low coefficient of friction for PCBN results in smooth weld surface.
Comparison between Fusion Welding and Friction Stir Welding | ||
Items | Fusion Welding | Friction Stir Welding |
Welding temperature | Above melting point | No more than 70% of melting point |
Microstructure | Solidified structure, severe segregation | Uniform fine-grained structure |
Distribution of residual stress | Big | Very small |
Weld strength | Low | High |
Energy consumption | High | About 65% of fusion welding |
Welding technology qualification | Required | Not require |
Operating environment | Tough | Good |
Friction stir welding technology has been successfully applied to aviation, aerospace, shipbuilding, trains, automobiles, electronics, electric power and other industrial fields. Specifically include: aerospace cylinder structure, aviation thin-wall structure, ship wide ribbed plate, high-speed train body structure, large thickness radar panel, automobile hub, container profile wall panel, radiators and heat sinks of various structures, eccetera.
