  1. Goals of SC-Air Chairmam of SC-Air Gong Shuili Co-Chairman of SC-Air LEE Sept. 15th , 2013

  2. AIMS To pay more attention to Structural Integrity Assessment works on aeronautical welding structures To promote the application of advanced welding technology in aircrafts To introduce Additive Manufacturing into aeronautical structures 1 2 AIMS 3 4 4 To introduce Surface Engineering Tech. into aeronautical structures

  3. AIMS Laser welding（Airbus） • Application of advanced welding technology in aircrafts— laserwelding All pictures refer to the internet

  4. AIMS The picture refers to the internet Laser welded thin-wall aircraft panel Process of the double-beam laser welding • Difficulties • Stability of the welding process (especially in double-beam welding) • Control of the welding defects (especially for aluminum)

  5. AIMS • Application of advanced welding technology in aircrafts— Electron beam welding (EBW) F-22 Raptor A380 Engine Application of EBW in aircrafts

  6. AIMS The picture refers to the internet 150mm The picture refers to the internet • Difficulties • Fatigue assessment of EBW structures

  7. AIMS • Application of advanced welding technology in aircrafts— Friction stir welding (FSW) Floor board of C17 Global MasterⅢ made by FSW FSW progress Application of FSW in aircrafts All pictures refer to the internet

  8. AIMS • Structural Integrity Assessment on aeronautical welding structures Fatigue Performance under high temperature Damage tolerance More works should pay attention
