Ultrasonic welding of pipes – modern joining technology

Ultrasonic welding is an innovative cable joining technology that uses ultrasonic vibration energy to create clean, durable and conductive connections. This process eliminates the need for adhesives, ensuring reliability and high quality in industries with the most stringent requirements.

How does ultrasonic welding work?

Ultrasonic welding

In the ultrasonic welding process, wires are joined by high-frequency mechanical vibrations. The energy of the ultrasound causes the material at the contact surface to become plastic, allowing the wires to form a homogeneous metallic bond.

Precision and quality for every industry

Advantages of the technology:

no need to use tin or adhesives,
high mechanical strength,
low electrical resistance,
repeatability and short production cycle time.

Ultrasonic welding at Starpol?

innovative technology without binders

Ultrasonic welding eliminates the need for additional materials such as tin or adhesives. This results in cleaner, more reliable joints that are free from the risk of corrosion or adhesive degradation.

durable and clean metallic connections

The process of joining wires using ultrasound creates a uniform metallic structure. The joints are extremely resistant to mechanical stress and guarantee stable operation even under difficult operating conditions.

low resistance and high conductivity

Homogeneous joints created during the welding process are characterised by minimal electrical resistance. This ensures maximum current conductivity, which is crucial in installations with high energy and signal requirements.

compliance with ISO 9001 and ISO 3834-2

All welding processes at Starpol are carried out in accordance with international quality standards. ISO 9001 and ISO 3834-2 certificates confirm repeatability, safety and full control over every stage of production.
