Application of ultrasonic welding in the automotive industry
Ultrasonic welding machines are widely used in the automotive industry:
In the automotive industry, welding is a key link in the manufacture of automotive parts and bodywork. It plays a special role in connecting the upper and lower. At the same time, there are many models of automobile products, complex forming structures, specialized parts production, standardization, and quality of automobile manufacturing. The comprehensive requirements of efficiency and cost determine that automotive welding is a multidisciplinary, cross-disciplinary and technologically integrated production process:
1. pairs of welded parts require high dimensional accuracy:
In order to ensure the assembly precision and dimensional stability of the product, it is required to minimize the precision deviation of the thin plate parts before welding and the thermal stress and deformation after welding;
2. pairs of welded joints have high performance requirements:
Not only must meet static and dynamic mechanical performance indicators, but also have severe low cycle fatigue performance requirements;
3. High quality and consistent requirements for batch welding production;
4. High tempo and high efficiency requirements for the welding production process;
5. Quality control and assurance of “zero defects”;
The requirements for monitoring and information management of automated welding processes are proposed.
