Reinforcement of Friction Plug Welds

A hole in a metal workpiece is filled by friction plug welding. The weld between the workpiece and the plug is reinforced by a weld land in the workpiece that surrounds one end of the plug. The weld land is formed by extruding a portion of the plug into a cavity in an anvil used in the welding proce...

Zusammenfassung:	A hole in a metal workpiece is filled by friction plug welding. The weld between the workpiece and the plug is reinforced by a weld land in the workpiece that surrounds one end of the plug. The weld land is formed by extruding a portion of the plug into a cavity in an anvil used in the welding process.
