FAQ:

Q: What’s the metal welding?

A: Ultrasonic metal welding was discovered by chance in the 1930s. It is similar to friction welding, but with the difference that the ultrasonic welding time is short and the temperature is lower than recrystallization; it is not the same as pressure welding because the static pressure applied is much smaller than that of pressure welding. It is generally believed that in the initial stage of the ultrasonic welding process, the oxide is tangentially vibrated out of the metal surface, and the protruding portion of the rough surface generates repeated micro-welding and destruction processes to increase the contact area and simultaneously increase the temperature of the soldering zone. High, plastic deformation occurs at the interface of the weldment. In this way, under the action of the contact pressure, the solder joints are formed when they approach each other to a distance at which the atomic attraction can act. The welding time is too long, or the ultrasonic amplitude is too large, so that the welding strength is reduced or even destroyed.

 

The service life of a welded joint depends on two aspects: one is material, the other is technology.

Material aspect: Ultrasound welding requires metal materials to have good flexibility (small mechanical loss in the process of acoustic transmission), so the most commonly used materials are aluminium alloy and titanium alloy, but Ultrasound metal welding requires wear resistance (higher hardness), which makes the selection of materials more difficult because of hardness. It seems that toughness and toughness are inherently opposed, which requires us to choose very high-quality materials. The high-quality steel materials we choose can better solve this contradiction, so as to improve the effective life of the welded joint as much as possible. A kind of

Processing technology: including processing technology and follow-up processing technology, the processing technology has been described in detail in the front, follow-up treatment includes heat treatment and parameter modification, based on the materials selected by our company, we have original heat treatment technology to ensure; after each welding head is made, the parameters are measured separately; and Adjustment to ensure production.

 

Amplitude parameter

Amplitude is a key parameter for the material to be welded. It is equivalent to the temperature of ferrochrome. If the temperature is not reached, it will not melt. If the temperature is too high, the raw material will be burned or the structure will be destroyed and the strength will be worse. Because each company chooses different transducers, the output amplitude of the transducer varies. By adapting varying ratio horn and welding head, the working amplitude of the welding head can be corrected to meet the requirements. Usually, the output amplitude of the transducer is 10-20 micron, while the working amplitude is generally about 30 micron, and the variation of the horn and welding head. The ratio is related to the shape of horn and welding head, the ratio of front to rear area and other factors. For shape, such as exponential amplitude, functional amplitude, step amplitude, etc., have a great influence on the ratio. The ratio of front to rear area is proportional to the total ratio. Your company chooses welding machines of different brands. The simplest method is to make the welded joints according to the proportional size of the welded joints, which can ensure the stability of the amplitude parameters.
