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.
Automated laser welding in battery production is highly efficient; however, manufacturers still struggle with quality and process stability issues. VIRO WSM monitors laser welding processes in real time and signals deviations immediately. This reduces NOK parts and interruptions.
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.
Because the common material of the battery housing is steel and aluminum and other refractory metals, it will also face various problems. In this paper reviews, the challenges and the latest progress of laser welding between different materials of battery busbar and battery pole and between the same materials of battery housing are reviewed.
In an automated high-speed laser welding line, the processes must operate with absolute stability. Severe deviations in the process, frequent interruptions in operation and a high rate of NOK parts ruin productivity and drive up costs. Similarly, all welds and contacts in the battery must be absolutely flawless.
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.
