Welding by energy is a method of controlling the ultrasonic welding process based on the amount of energy delivered to the joint, rather than the duration of the welding cycle. In this method, the ultrasonic generator is programmed to deliver a specific amount of energy to the joint, based on factors such as the material being welded, the part geometry, and other process variables.
To achieve a consistent, high-quality weld using welding by energy, it is necessary to carefully control both the amplitude and the welding time of the ultrasonic energy, as well as the applied pressure and other process variables. By measuring the amount of energy delivered to the joint during each welding cycle, it is possible to monitor and control the welding process in real time, and adjust the process parameters as needed to achieve optimal results.
Welding by energy is a popular method of ultrasonic welding control, as it offers a high degree of precision and consistency, and can be used to optimize the welding process for a wide range of materials and part geometries. However, it is important to note that welding by energy alone may not be sufficient to ensure consistent, high-quality welds, and other factors such as pressure, amplitude, and tooling design must also be carefully controlled to achieve optimal results.
