20k 3000w Ultrasonic Equipment for High-speed Welding of Plastic Copper Aluminum Metal Materials


Description:

Ultrasonic metal welding is a technology that utilizes the heat generated by ultrasonic vibration to achieve the welding of metal materials. It is a very effective metal welding method that can be used to weld various metal materials, such as aluminum, copper, steel, etc.

Material selection for ultrasonic metal welding:
The plasticity of ultrasonic welding materials refers to the reversible deformation that can occur when the material is subjected to pressure and heat during the welding process, that is, it can undergo plastic deformation without rupture or fracture. This plasticity is the key to achieving the formation and connection of metal joints during the welding process.
In ultrasonic welding, the formation of the welding joint requires a certain amount of pressure to be applied to the contact surface, and sufficient heat to be generated in the welding area to melt the metal and form the weld seam. Therefore, welding materials must have sufficient plasticity to withstand the applied pressure and heat during the welding process without fracture or rupture.
Generally speaking, metal materials with better plasticity are more suitable for ultrasonic welding. For example, metals with good plasticity such as aluminum and copper are often used in ultrasonic welding. These materials can maintain their continuity when subjected to compression and deformation during the welding process, and recover to a stable shape after welding is completed.
In contrast, brittle materials such as certain cast iron, stainless steel, etc. may be more prone to cracking or fracture during welding because of their lower plasticity and difficulty in withstanding deformation and stress during the welding process.
Therefore, in ultrasonic welding, selecting materials with appropriate plasticity is crucial for achieving high-quality welding. In addition, factors such as the melting point and thermal conductivity of the material need to be considered to ensure the controllability and stability of the welding process.


The process of ultrasonic metal welding can be divided into several key steps:
1. Material preparation: Prepare the metal materials that need to be welded to ensure the cleanliness and smoothness of the joint surface.
2. Assembly: Correctly assemble the metal joint to be welded into the welding fixture to ensure tight contact between the contact surfaces.
3. Ultrasonic vibration transmission: Apply ultrasonic vibration to the welding joint and apply a certain pressure to generate frictional heat on the contact surface.
4. Heating and melting: Friction heat causes local heating of the metal joint. When the temperature reaches the melting point, the metal begins to melt and form a weld.
5. Welding completion and cooling: After welding is completed, stop ultrasonic vibration and let the weld gradually cool to form a stable welding connection.
Ultrasonic metal welding has many advantages, such as fast welding speed, no need for filler materials, no obvious oxidation and splashing, etc. It is widely used in many fields, including automotive manufacturing, electronic equipment manufacturing, aerospace, and medical devices. However, ultrasonic metal welding requires high plasticity of metal materials and requires careful control of the properties and welding parameters of the welding material to ensure welding quality and connection strength.
