Force-Controlled Joining Process
A method where the contact pressure during welding is continuously monitored and adjusted. This ensures a uniform mechanical preload of the parts to be joined.
Physicochemical Working Principle
The force-controlled joining process regulates the contact pressure during welding to ensure that the joining partners are uniformly preloaded. This prevents stress peaks and improves weld quality.
Metallurgical Relevance & Welding Risks
Uneven preload can cause stress peaks, which can lead to cracks or hot cracks in the weld. The force-controlled joining process minimizes these risks and ensures high joint strength.
Shop Practice & Action Instructions
Use a force controller that monitors and regulates the contact pressure in a defined range from 50 to 150 N/mm². Ensure that the joining partners are correctly aligned before welding and no stress peaks occur. The regulation should be checked at least every 30 seconds.
