| Abstract: | The influence of different welding line energy and different preheating temperatures on the mechanical properties of 5083-H111 aluminum alloy MIG welded joints is studied respectively through tensile tests,bending tests and hardness tests.The results show that under different line energy and preheating temperatures,the tensile strength of the welded joints of 5083-H111 aluminum alloy (4 mm) are good and meet the standard requirements,the bending properties of welded joints are good,the hardness value of each region varies a little and has no significant softening phenomenon. |
