Friction Stir Welding

Welcome to the World of Friction Stir Welding

Friction Stir Welding (FSW) is a revolutionary solid-state joining process. Learn more about this innovative technology and its applications.

About Friction Stir Welding

Friction Stir Welding was invented in 1991 by The Welding Institute (TWI). It is a solid-state welding process that uses a non-consumable tool to join two facing workpieces without melting the workpiece material.

The FSW Process

The FSW process involves the following steps:

• A rotating tool with a pin and shoulder is plunged into the joint between two pieces of material.
• The tool moves along the joint line, creating frictional heat.
• The material softens and is stirred together by the tool, creating a solid-state weld.

Applications of FSW

FSW is used in various industries including aerospace, automotive, and shipbuilding due to its ability to produce high-quality welds with minimal distortion.
