Future Joining Technologies: FSW Using Machining Centers
In recent years, the technology for joining metals has evolved, leading to the development of a joining method that operates at lower temperatures and without contamination compared to traditional welding techniques. This method is called FSW (Friction Stir Welding). FSW does not melt the metals to join them; instead, it uses a special tool and is performed on a machining center. Because this method operates at a low joining temperature, the deformation caused to the metals is minimal, significantly shortening the distortion correction process. Additionally, since it is performed using NC (numerical control), there is an advantage of eliminating variations caused by differences in the skills of operators (such as welders). Automated construction using a machining center ensures consistent product quality. Furthermore, it does not produce harmful rays, sparks, or fumes, making it environmentally friendly. FSW (Friction Stir Welding) is expected to gain increasing attention in the future and is said to become an indispensable technology in the manufacturing of metal products.
