Emerson introduces new ultrasonic metal welder for bonding larger batteries, conductors and wire terminations

25 January 2023

Emerson’s new Branson GMX-HP ultrasonic metal welder combines greater power and downforce, essential for larger welds required by electric vehicles, batteries and energy storage systems, with a modular equipment design and features that simplify installation and automation for machine builders and manufacturers.

The new GMX-HP features increased weld power, furnished by a high-capacity 8 kW, 20 kHz power supply. Welding power is transmitted through a direct-press actuator equipped with dual linear bearing guides, precision distance sensors and a dynamic pressure trigger that deliver greater part-holding downforce with the high stability needed for repeatable weld quality.

These characteristics make the GMX-HP welder an excellent choice for ultrasonic welding of larger-diameter conductors, terminations and busbars essential for increased power-carrying capacity, or for bonding the thicker stacks of anode/cathode films used in high power-density batteries or energy storage systems.

The GMX-HP welder is also designed for optimal flexibility and productivity, from automation design through long-run manufacturing. Manufacturing engineers, automation experts and machine builders will appreciate the flexibility of the welder’s modular design, which accommodates base mounting, rear-gantry or top-gantry mountings to simplify configuration, installation and operation of multimachine automated welding systems.

Production managers and operators will note a new quick-release modular actuator that enables rapid, but precise, change-outs of weld “horns” or entire weld “stacks” to meet varied production requirements.

“Manufacturers are seeking better ways to build more powerful batteries and energy storage systems for everything from electric vehicles to renewable energy systems. The GMX-HP welder lets users scale up designs without sacrificing reliability or consistency,” said Alex Yeung, global product manager, metal welding for Emerson.

Built into the weld power supply, the welder’s programmable digital controls can manage the welding process in multiple modes: time, energy, peak power and distance. These versatile weld modes ensure the added precision required to maintain tight weld process control despite occasional variations in part surface quality or cleanliness. Production and quality assurance managers can track weld output, quality and yields with the help of the full array of weld-data collection and storage capabilities available in the GMX-HP weld power supply.
