Definitions
- the welding forming method refers to machine-adding standard aluminum alloy plates to the required size, and then welding the plates together to form a cavity.
- Conventional aluminum alloy welding methods include arc welding, laser welding, gas welding, flame welding, plasma welding or hybrid welding. For aluminum alloy plates with a thickness of 20 mm or more in this application, the energy density of gas welding, flame welding, etc. is too small, and is not suitable for welding thick plates.
- a plasma arc-laser hybrid welding method for a rectangular cavity of aluminum alloy with high sealing property includes the following steps:
- the seventh step adjust the cavity to the posture where the No. 3 board 3 is placed at the bottom, and use the optimized welding process parameters to weld the No. 4 board 4 with the No. 1 board 1, the 2nd board 2, the 5th board 5, and the 6th board 6
- the optimized welding process parameters used are:
