Emerson announces its new Branson™ GMX-20MA ultrasonic metal spot welder, an advanced spot welder that bonds nonferrous metals, including bus bars, foils, switches, and wire terminations in automotive electrical systems, electric vehicles, batteries and battery packs, power storage systems and related applications.
The GMX-20MA metal spot welder is built around an all-new, rigid pneumatic actuator with dual linear bearings and a digital load cell to ensure smoother vertical motion and more precise downforce control for maximum weld quality and repeatability. Actuator travel and tool positioning relative to the welded parts are tracked and measured using a linear encoder. Once tooling/part contact is made, a digital load cell measures and maintains a precise level of actuator downforce on the parts, ensuring that weld energy is accurately delivered and consistent weld quality is assured from one weld to the next.
