Abstract:The characteristics of welding for 7xxx series aluminum alloys were combined, and the selection and optimization of wires were introduced. Three new welding methods, such as double wire MIG welding, laser-MIG hybrid welding and friction stir welding, were stated. Compared with traditional welding methods, the three new methods have superiority and foreground in the welding of 7xxx series aluminum alloys. Alloying optimization design of base metal and wire for 7xxx series aluminum alloys, developing of new welding method are the important research direction in the future.

 

Key words: 7xxx series aluminum alloy; welding; selection of wire; welding method
