The invention discloses a laser welding method and laser welding equipment for 7-series aluminum alloy and a storage medium. The laser welding method for the 7-series aluminum alloy comprises the steps that the 7-series aluminum alloy needing to be welded is stacked or lapped together, and silicon is adopted as a welding filling material; and the 7-series aluminum alloy is welded through laser welding. According to the laser welding method for the 7-series aluminum alloy, silicon is filled when the aluminum alloy is subjected to laser welding, in the laser welding process, a welding material is subjected to the violent heating and cooling process, and in the process, the material is subjected to remelting, redistribution of the silicon content and rapid change of the internal stress state. In the weld nugget area of the weld joint, silicon and aluminum materials are firstly heated and melted and then rapidly cooled, growth of silicon and aluminum matrixes is controlled under the effect ...

The invention discloses a laser welding method and laser welding equipment for 7-series aluminum alloy and a storage medium. The laser welding method for the 7-series aluminum alloy comprises the steps that the 7-series aluminum alloy needing to be welded is stacked or lapped together, and titanium alloy is adopted as a welding filling material; and the 7-series aluminum alloy is welded through laser welding. When the laser welding method for the 7-series aluminum alloy is used for welding, titanium and aluminum can form peritectic reaction, a refractory Al3Ti compound is generated, and the Al3Ti compound is a fine refractory mass point and can become a non-spontaneous solidification crystal nucleus when the liquid aluminum alloy is solidified, so that the effect of refining crystal grains and dendritic crystals is achieved. The radius of the titanium atoms is larger than that of the aluminum atoms, the titanium atoms are molten in molten aluminum, the surface defects of the aluminum alloy ...

The invention discloses a laser welding method and laser welding equipment for 7-series aluminum alloy and a storage medium. The laser welding method for the 7-series aluminum alloy comprises the steps that the 7-series aluminum alloy needing to be welded is stacked or lapped together, and nickel is adopted as a welding filling material; and the 7-series aluminum alloy is welded through laser welding. According to the laser welding method for the 7-series aluminum alloy, nickel is filled when the 7-series aluminum alloy is welded, the nickel forms NiAl3 and other metal compounds in the aluminum alloy, the strength and hardness of the alloy can be improved, the tendency that a Fe compound in the alloy becomes a block is achieved, and the harm of the impurity Fe in the aluminum alloy is reduced. The appearance of a welding seam filled with nickel is smoother, and the excess weld metal is lower. Nickel can neutralize Cu in the aluminum alloy, the content of copper is reduced, harmful effects ...
