摘要
钠硫电池的工作温度在300～350℃,并产生高的气压。为了保证电池的安全和稳定,钠硫电池的焊接要满足:良好的密封性、合理的焊接深度,并在焊接时工件内侧产生的温度要低于90℃。通过300 W YAG焊接机和500 W连续激光焊接系统的焊接试验对比,结果表明,500W连续激光焊接表面质量更好,焊接效率更高,并且能够满足钠硫电池对焊接质量的要求。
Sodium-sulfur battery works at 300-350 ℃,and produces high air pressure.In order to ensure the safety and stability,the sealing must be good and penetration must be reasonable.Moreover,the inside temperature during the welding should be lower than 90 ℃.300 W YAG welding machine and 500 W CW laser welding system were compared by experiment.The results show that the surface qualities of 500 W CW laser welding is much better and the efficiency is higher.500 W CW laser welding system can satisfy the welding quality of NaS battery.
