Ultrasonic Metal Welding Online Monitor-Quality Control

Ultrasonic metal welding (USMW) is a common used manufacturing technology for cell, module or pack assembly of Lithium-ion battery systems of pouch type. Since every single joint can affect the efficiency and safety of the entire battery system, quality fluctuations of the joint are one of the greatest challenges. Despite its industrial spread in battery manufacturing, USMW has a large number of influencing variables that may affect the bond quality but cannot be detected 100% failsafe with existing monitoring methods. 

The SBT Ultrasonic Metal Welding Online Monitor is critical in identifying welding issues, detecting defects and improving battery quality. The welding machine system is equipped with a real-time detection system and integrated sensors for data collection both inside and outside the machine. Self-learning algorithms are used to automatically control the welding output within the appropriate range.

Real-time detection of changes in welding status during the ultrasonic dynamic welding process is performed. The system effectively detects welding defects and provides real-time, non-destructive testing and instant online alerts to prevent batch losses.
