| Abstract: | Incompatible metallic cut cutter made from 45 and W18Cr4V was connected by friction or flash welding. The microstructure and properties in welding joint were compared and analyzed. Together with the reason of lower strength and fracture toughness were investigated in the soldering seam zone of the flash welded joint. The excellences of the friction welding and joint formation were illustrated. The optimal welding parameters were given for friction welded joint. The results showed that friction welding of 45 and W18Cr4V cut cutter improved the microstructure and properties in soldering seam zone of welded joint. |
| Keywords: | incompatible metal friction welding flash welding welded joint fracture toughness |
