Factors affecting the quality of ultrasonic welding

 

1. Material of welding material: Generally speaking, the quality of welding is related to the physical properties of the material and the modification of the material. The physical properties of the material include the material's elastic modulus, friction coefficient, thermal conductivity, melting point, etc. The welding quality of the object and the material The modulus of elasticity, coefficient of friction, and thermal conductivity are directly proportional to its density and melting point. Material modification refers to the addition of some fillers under appropriate process conditions to improve the original properties of the material, so that it can meet the needs of customers Use requirements. Adding some materials with similar properties under suitable process conditions can improve the strength of the welded joint.

 

2. The contact surface of the welding head and the weldment: the cleanliness of the welding surface and the roughness of the material surface will affect the welding quality of the weldment. Increasing the surface roughness of the material can improve the welding quality; the higher the cleanliness of the welding surface, The welding quality is also higher.

 

3. Other factors: the process parameters of the ultrasonic welding technology, the structure of the welded parts, the connection form, the amount of melting during welding, the power of the ultrasonic, etc. In order to achieve the best welding effect, these factors must be carried out in the product development stage. Considering.
