| Popis: | Plasma-MIG hybrid welding and MIG welding of 5083 marine aluminum alloy was carried out. The influences of parameters of welding process on the weldments morphology were investigated in order to optimize the welding process parameters. The macrostructure, microstructure, tensile and bending properties of the optimized joint were studied. The results show that Plasma-MIG hybrid welding not only has a synergistic effect of Plasma and MIG welding but also has a high welding efficiency. Welding speed, Plasma current and MIG current have a significant effect on welding penetration and welding morphology. Meanwhile, the ductility and strength property of weld joint was qualified though the bending test and tensile test. The average tensile strength of weld joint is about 285MPa at room temperature, about 86% of the base metal. |
