Telsonic’s superior torsional SONIQTWIST® welding know-how has been efficiently utilized in a groundbreaking resolution for fixing silver-plated aluminum busbars utilizing screws. This innovation, developed in collaboration with the KERN-LIEBERS Group, a producer of precision stamped elements, guarantees to set new requirements for reliability and conductivity in electrical connections for industrial purposes.Â
The Problem: Securing Silver-Plated Aluminum BusbarsÂ
The KERN-LIEBERS Group has pioneered a way to coat aluminum busbars inline with silver. This silver coating enhances the busbars’ conductivity however poses a problem for safe attachment utilizing screws, as a result of rest properties of aluminum. The answer requires the mixing of a copper sleeve into the busbar, offering a sturdy and electrically conductive connection that permits for screw fixation.
The Resolution: Integrating Copper Sleeves with Ultrasonic WeldingÂ
To implement this resolution, a copper sleeve is positioned right into a pre-punched gap within the busbar. The sleeve is designed with an outsized collar to facilitate the transmission of torsional ultrasonic vibrations via a sonotrode. This course of welds the copper sleeve to the silver layer, making certain the integrity of the silver coating is maintained.Â
Telsonic’s torsional SONIQTWIST® know-how – the torsional welding system TSP3000.
Configuration Benefits
The mixing of silver coating expands the compatibility of ultrasonic welding to new aluminum alloys. Ultrasonic welding affords a process-secure and long-term steady connection between dissimilar metals with minimal electrical resistance. The manufacturing of busbars with punched holes is cost-efficient, and integrating the silver coating into the manufacturing course of eliminates further transport prices for exterior coating.
