CHINA NBC-UWL11A Ultrasonic metal spot welding machine 40KHz

NBC-UWL11A（40K）

Ultrasonic metal spot welding machine

Metal welding for winding and laminating process, touch screen operation, ultrasonic Frequency 40KHz, welding head with wear-resistant material, welding time 0.01-2S seconds, no spark during welding.

Introduction

Ultrasonic metal spot welding machine is generally used for metal welding in coiling and lamination processes. It has the characteristics of small size, beautiful appearance, easy operation, solid structure, stable and safe use.

Principle

The principle of ultrasonic high-frequency vibration friction is used to convert the energy of ultrasonic vibration into friction energy and transmit it to the metal surface to be welded. When friction generates heat and applies pressure to it, the metal structure molecules are fully activated to form between molecular layers. Fusion of new equipment.

main feature

• Touch screen interface, intuitive and convenient, with automatic frequency tracking.

• There are no traces of oxidation. Ultrasonic waves have a cleaning function. Even if there are contaminants or oxides on the metal surface, it can be welded well without surface treatment.

• All workpieces do not need to be pre-processed and can be welded without soldering tin or soldering oil additives, which is economical and convenient.

• The welding head is made of wear-resistant materials for long-lasting durability.

• The internal resistance of the solder joint is small. After welding, the conductivity is good, and its resistivity is extremely low, close to zero.

• The welding time is very short, and welding can generally be completed instantly within 0.01-2 seconds.

• The solder joints are firm, the working temperature does not exceed its annealing temperature, and the metallographic structure of the workpiece is not changed. Its melting strength is stronger than other welding methods, and the welding interface is neat and clean.

• Welding has low cost, fast speed, easy operation and convenient maintenance.

• No sparks are produced during welding, so the operator is safe and secure. There is no smoke smell and no air pollution.
