This technique, used in particular by orbital and radial riveters, offers many advantages over traditional methods.
Creep joining is based on the principle of the progressive deformation of a material under the effect of a stress applied over time. Unlike traditional joining methods such as welding or screwing, which can lead to significant local stresses and damage to parts, creep joining allows for a more uniform distribution of stresses, thus reducing the risk of premature failure.
Advantages of creep assembly:
– Superior strength: By allowing controlled deformation of the material, creep assembly strengthens the connection between parts, providing superior resistance to mechanical stress and vibration.
– Design flexibility: This method allows parts of complex shapes or different materials to be assembled, thus providing greater freedom in product design.
– Cost savings: a short cycle time translates into higher productivity. The high level of process repeatability does not require 100% control of the assemblies produced.
Tips for optimizing processes:
– Choose the right material: The success of cold flow forming depends largely on the material used. Make sure to select materials that are compatible and have adequate deformation properties.
– Control process parameters: Pressure and time are critical parameters to control during flow assembly. Be sure to adjust these parameters according to your part specifications and quality goals.
– Ensure adequate training: Training your staff is essential to ensure efficient and safe processes. Invest in training and certification programs to ensure mastery of techniques and equipment.
