Patent No. EP3840941 (titled "Method For Producing A Welded Connection, And Welding Device") was filed by Agru Kunststofftechnik Gesellschaft on May 22, 2019. The application was issued on Mar 13, 2024.

Patent Summary

A method for connecting a thermoplastic line element to a connecting element comprises providing a connecting element with a thermoplastic body containing an embedded heating element for generating heat in a welding region. The line element is joined to the connecting element, and a welding device is provided to perform the weld. Information regarding the connecting element is input into the welding device. The device generates heat in the welding region to weld the components. The welding device is configured to stop the welding process before the planned duration ends or output an error message if an error criterion is met. This error criterion is reached when a specific number of error messages are accumulated in an error counter implemented within the welding device.
