| Abstract: | The effect on welding depth profile under various welding parameter while using YAG LASER、GTAW、GTAW+LASER to weld aluminum alloy is studied. The mechanical properties of LASER reacting to arc are discussed. The result shows that the welding line profile is better and HAZ is smaller by YAG LASER+GTAW. The welding speed and penetration are improved prominently comparing with GTAW to realize aluminum alloy welding with low power LASER machine. Laser、GTAW are the perfect methods for aluminum alloy welding. |
