Aluminum alloy has the advantages of low density, high strength and good corrosion resistance. Therefore, it has been widely used in automobile industry, new
energy, aerospace and construction industry.
At present, laser welding has been widely used in the production and manufacturing of aluminum alloy products. Compared with traditional welding methods, laser
welding can provide higher production efficiency, better weld quality, and realize high-precision welding and automation of complex structures.
Laser welding is a technology that radiates high-intensity laser to the metal surface, melts the metal through the thermal coupling between laser and metal, and
then cools and crystallizes to form weld.
According to the thermal action mechanism of laser welding, it can be divided into thermal conductivity welding and deep penetration welding. Thermal conductivity
welding is mainly used for packaging welding or micro nano welding of precision parts; Laser deep penetration welding is mainly used in the welding of materials
requiring complete penetration. The welding process will vaporize the materials and there will be keyholes in the molten pool. It is the most widely used laser
welding method and the preferred method for aluminum alloy welding.
