Laser Welding Machine Application in New Energy Automobile
New energy technology has been applied in various industries, especially in the field of automobile.
As the core part of new energy, the battery determines the performance of the whole vehicle. So the production of reliable guaranteed, precision and accurate battery is the decisive factor of new energy automotive industry.
Laser welding is well known for its stability and accuracy. Therefore, laser welding machine has also become the first choice of new energy battery manufacturers.
▂
Laser welding used in battery welding is to use high energy laser pulse to locally heat the small area of the battery. The energy of laser radiation spreads to the interior of the material through heat conduction, and then the material is melted to form a specific melting pool.
Laser welding can realize spot welding, butt welding, stack welding, sealing welding, etc., High depth-to-width ratio, small weld width, small thermal influence area and deformation, fast welding speed, smooth and beautiful welding line.
No need to process the welding power battery and other parts after welding. Welding quality is high, no pores, accurate control, small precise focus, high positioning accuracy, easy to realize automation.
In a word, laser welding technology perfectly makes use of various advantages of laser beam for welding tasks. In the future, laser welding technology will be more flexible to adapt to the welding tasks of lithium battery modules with different new energy power battery materials and different shapes. Will be the emerging welding technology urgently needed by manufacturing industry.
