Rotary friction welding is a process in which two parts are joined together by the heat generated from friction between the parts. The rotational speed of the parts is an important factor in the welding process. The rotational speed of the parts should be adjusted to achieve the desired weld joint.
In rotary friction welding, the rotational speed of the weld joint can have a significant impact on the quality of the weld. In general, the rotational speed should be selected based on the material properties of the weld joint, the size and geometry of the weld joint, and the desired welding parameters like temperature and force. You also have to consider a few different factors that can influence the rotational speed of a weld joint in rotary friction welding:
Material properties: The material properties of the weld joint, such as the yield strength, tensile strength, and ductility, can affect the rotational speed that is required for the weld. For example, materials with a higher yield strength may require a slower rotational speed in order to achieve the desired welding parameters.
Size and geometry: The size and geometry of the weld joint can also influence the rotational speed that is required. Larger weld joints may require a slower rotational speed in order to achieve the desired welding parameters, while smaller weld joints may require a faster rotational speed.
Desired welding parameters: The desired welding parameters, such as the temperature and force, can also affect the rotational speed that is required. For example, higher temperatures may be achieved at slower rotational speeds, while higher forces may be achieved at faster rotational speeds.
Carefully consider these when selecting the rotational speed for a weld joint in rotary friction welding. This will help to ensure that the weld joint is produced with the desired properties and characteristics.
The most important process parameter is rotational speed because it affects the amount of friction that the tool generates, and consequently, the amount of heat produced. Rotational speed has a larger effect than the other process parameters or the torque because increasing the spindle speed increases the heat generation and workpiece temperature, which then reduces the torque.
It depends on the materials of the plates, the thickness of the plate, ....
