What are the requirements for customization of ultrasonic spot welding head?

What is ultrasonic spot welding head:

 Ultrasonic spot welding head is general designation of all ultrasonic transmitting terminals ans an indispensable part of ultrasonic welding equipment. Its function is to couple the ultrasonic wave generated by the transducer into the processed object. Because it needs to transmit ultrasonic wave, the spot welding head must work in the resonant condition, that is, its natural resonant frequency should match the transducer. Secondly, the amplitude should be uniform, and the shape of the end face of the spot welding head should adapt to the shape of the welded work-piece.The material of ultrasonic spot welding head is basically made of titanium alloy, magnesium alloy or powder metallurgical steel, etc.

二、Customization of ultrasonic spot welding head:

Many customers intuitively think that the design and production of spot welding head must be very simple. In fact, this is misleading. When using a spot welding head that is not properly processed or has not been tuned, it will bring valuable loss to your production- it will damage the welding effect, even more serious, it will directly cause damage to the transducer or generator.

Therefore, the design of the spot welding head is by no means as simple as its appearance. On the contrary, it requires many professional common sense and technology- how to ensure that the spot welding head can effectively transfer the mechanical oscillation converted by the transducer to the work-piece, form a stable welding effect- Shouchuang hardware electronics Co.,Ltd, we still believe that only through strict tests and quality control can we produce better spot welding heads. After using ultrasound mold analysis software, we imitate the actual working conditions of spot welding head, our engineers perfectly combine the acoustic characteristics and mechanical characteristics of spot welding head to design products that meet customers’ need.

三、Ultrasonic spot welding head is divided into three types according to mold materials:

1.Aluminum Magnesium mold is used for the production of Oscillation system(amplitude variation) and spot welding head. This materials had extremely high mechanical yield strength, high hardness and strong thermal conductivity, and is the ambitious ultrasound mold ingredients; but aluminum is not wear-resistant, suitable for general welding requirements.

2.Titanium alloy mold:

It is used for connecting continuous continuous vibration, with high starting Property, good heat conduction, high hardness and higher cost than magnesium alloy, but it is more durable and wear-resistant magnesium alloy mold.

3.Imported Hard Alloy steel mold:

Imported alloy materials has extremely high hardness, which is used for continuous welding or welding with wear resistance, low heat conduction, high mechanical loss to ultrasonic wave, low use cost, but the manufacturing process is relatively complicated.

The above is the summary we have made for you. I hope it can be helpful to you.
