Process Parameters: Frequency 20kHz | Welding Power 3000W | Welding Time 0.3~0.6s | Amplitude 50~70μm Applicable Terminals: Copper/Brass/Tinned terminals, compatible with wire diameters 1.5mm² ~ 25mm² Welding Results: Shear force ≥ terminal body strength | Contact resistance ≤ joint body resistance × 1.2 | Degradation <5% after 200°C high-temperature aging Process Advantages Ultrasonic terminal welding eliminates issues of inconsistent terminal deformation and unstable contact resistance found in traditional crimping processes. By precisely controlling welding energy and amplitude, it achieves consistent bonding between copper wires and tinned terminals, with neat and burr-free weld appearances, meeting the strict quality requirements of the automotive and new energy industries. ▼ Terminal Welding Sample Physical Image Display
