EV Battery Welders

EV Battery Welders

For larger stacks of foils, tabs, and busbar welding applications, TECH-SONIC developed a direct-drive, heavy-duty model of 3.6kW ultrasonic spot welding machine, model US-3620SH. This direct drive ultrasonic spot welding machine uses a larger servo motor directly mobilizing the weld head for increased control and efficiency allowing users to increase their capabilities without increasing power requirement. TECH-SONIC has gone beyond the latest ultrasonic metal welding technology by adding servomechanism control to ultrasonic welding. Thus, producing a closed-loop control welding process that responds to the various dynamics of today’s critical welds. Moreover, CLC ultrasonic spot welding machine provides accuracy, repeatability, and reliability.

Dynamic Force and Amplitude Control™

with Multi-Step Welding

  •  Capability of over 20 weld steps with unique force and amplitude parameters
  • Ability to change and adjust force and amplitude during the weld cycle to optimize welding parameters for each specific wire application
  • Direct-drive servo motor provides the ability to weld thicker stacks to busbar utilizing a wider horn

Load Cell Force Feedback

Single Micron Resolution

  • Consistent measurement and ultrasonic output produce high cPk values
  • Measurement of pre-weld and post-weld height and width
  • Cross section area measurement and calculation for additional quality control

Higher Efficiency and Quality Control

  •  Driven by Servo Motors
  •  Longer Tooling Life
  • Capability to reduce excess stress on foils and tabs by using ideal welding parameters; limits rifts in material
  • Soft touch landing on weld materials controlled by servo
  • Prevents tearing damage to surface layers of foils or tabs on impact
  • Option for a set home position, lower level than fully open position, to shorten cycle times
