dc.description.abstractIn this study we conducted single V-groove butt welding (GTAW) on three types of heat treatable aluminum alloys 2024-T351, 6061-T6 and 7075-T6 and compared the angular distortion levels of the three aluminum alloys at different Vee preparation angles with or without restraint. Experimental results demonstrated that when the Vee preparation angle was 0 degrees (l-shaped groove), the angular distortion level of the restrained weldment can exceed that of the unrestrained weldments. Moreover, when. the Vee preparation angle was 45 degrees, 60 degrees or 90 degrees, the restrained weldment had lower angular distortion than the unrestrained weldments. The single Vee preparation angle (amount of filler metal) in butt welding affected the angular distortion of the weldment. Without restraint, the angular distortion tended to increase with the single Vee preparation angle. Meanwhile, the angular distortion tended to decrease when the single Vee preparation angle was 60 degrees. Additionally, a restrained weldment had high angular distortion when the single Vee preparation angle was 0 degrees. Notably, the angular distortion tended to reduce with increasing single Vee preparation angle. The angular distortion of the weldment was minimized at an angle of 60 degrees. However, the angular distortion increased when the Vee preparation angle exceeded 60 degrees. The high-temperature yield strength of a material also affected its angular distortion. Angular distortion increased with high-temperature yield strength. Experimental results also showed that, from the strongest to the weakest, the high-temperature yield strength of the three types of aluminum alloys followed the order 6061-T6 and 2024-T351 > 7075-T6.en_US
