4. Summary and Outlook Laser welding is a welding method with high energy density and non-contact and accurate heat input control, which can provide reliable weldability for the welding between dissimilar materials in the battery system of electric vehicles.
Laser welding is considered to be the most promising connection method because of its easy automation, high accuracy, small heat-affected zone, non-contact process, high process speed and ease of welding different metals. Laser welding is an efficient and precise welding method using high energy density laser beam as heat source.
There are many parts that need to be connected in the battery system, and welding is often the most effective and reliable connection method. Laser welding has the advantages of non-contact, high energy density, accurate heat input control, and easy automation, which is considered to be the ideal choice for electric vehicle battery manufacturing.
Laser welding is an efficient and precise welding method using high energy density laser beam as heat source. Due to heat concentration, fast welding speed, small thermal effect, small welding deformation, easy to realize efficient automation and integration [15, 16, 17], it is more and more widely used in power battery manufacturing.
