Analysis and improvement of laser welding pseudo weld causes of power battery connectors
Thepseudo welding of the power battery connection would affect the strength and overcurrent of the module,which would have an adverse effect on the function of the product.In this paper,the reasons of the joint sheet pseudo welding were analyzed from the welding process,and the influence of welding process param-eters on the joint penetration is studied.The results showed that in the production of power battery laser weld-ing,the main causes of pseudo welding a were dirty galvanometer,too small dust extraction speed,too large gas protection gas flow,residual glue in the connection sheet,laser power attenuation,and out-of-control defocus.The production process needed to effectively control the above factors.
