Double pulse lithium battery spot welding machine is a key equipment used for welding the solder joints of lithium batteries. In the welding process, strict inspection work must be carried out to ensure the quality of the solder joints. There are various methods for testing the qualification of solder joints, such as visual inspection, resistance testing, ultrasonic testing, etc.

Visual inspection can observe the shape of the solder joint and whether the welding is uniform. Resistance testing can detect whether the resistance value of the solder joint meets the requirements. Ultrasonic testing can detect whether there are defects such as pores or cracks in the solder joint.

Only through comprehensive testing can we ensure that the quality of solder joints meets the standard requirements. The qualification testing of welding points for dual pulse lithium battery spot welding machines is crucial, as it relates to the safety and stability of the product.

Therefore, in the production process, it is necessary to strictly follow the welding point qualification testing process to ensure that every welding point of the lithium battery meets the standards, thereby ensuring the quality and performance of the product. Through scientific testing methods and strict quality control, the qualification rate of welding points in dual pulse lithium battery spot welding machines can be effectively improved, ensuring smooth production.
