Ultrasonic Welding Machine – Advanced Solution for Automotive Wire Splicing
Discover VietSonic’s ultrasonic welding machine – a modern solution for automotive wire splicing that requires no external heat, offers high durability and conductivity, and is perfect for automated production.

Ultrasonic Welding Machine – Advanced Solution for Automotive Wire Splicing

1. Overview

The Ultrasonic Welding Machine from VietSonic, researched and manufactured in Vietnam by Dr. Nguyen Thanh Hai – Lecturer at Ho Chi Minh City University of Technology (HCMUT), is equipment that applies ultrasonic frequencies of 20 kHz or higher to heat and bond soft metal materials like copper and aluminum in an environment free of external heat or solder flux.

2. Operating Principle

  • The device generates ultrasonic waves (typically 20 kHz – 35 kHz) transmitted through a welding horn (sonotrode).
  • Under pneumatic pressure, mechanical waves create friction at the wire splice interface, forming a tight and durable solid-state bond without melting the material like traditional heat welding.
  • The process generates no sparks and requires no flux, making it eco-friendly – optimized for automotive manufacturing.

3. Key Benefits for Automotive Wire Welding

Advantage Description
High Mechanical Strength Although not fully melted, the ultrasonic weld provides a robust solid-state linkage with better load-bearing and vibration resistance than legacy methods.
High Speed & Productivity Completes the splice in seconds, suitable for industrial automation lines.
Safe & Eco-friendly No high temperatures, no emissions, no deformation of conductors, and no damage to the insulation layer.

4. Practical Applications in Automotive Manufacturing

The VietSonic video (uIQagM-MPtE) details the process:

  • Preparation of wire ends (copper, aluminum).
  • Placement into the positioning jig.
  • The machine applies ultrasonic pulses + pressure to create a tight splice with a flat surface, ensuring high quality control.


Primary Applications:

  • Welding main splices on automotive wire harnesses.
  • Protection and reinforcement of sensor clusters and IC wires.
  • Labor saving, suitable for high-level quality control (QC).

5. Why Choose VietSonic?

  • Localization with Euro-American Standards: VietSonic inherits technology from Germany (Herrmann) and the USA (Dukane), manufacturing in Vietnam with quality comparable to imported welders.
