Cable welding

high-quality non-ferrous metal compounds with maximum service life and durability

Welding of copper cables or other alloys with or without a coating

Through the connection of cables, the so-called splicing (cable welding), through connectors and end connectors can be realized. Resistance welding technology makes it possible to reliably connect copper cables or other alloys with or without a coating. With the right equipment for every range, cable connections from 0.1 to 400 mm² can currently be implemented.

In the case of large quantities, a system variant with an application-specific tool adapted to the individual workpiece is recommended, while our automatic welding heads with different transverse positions are the better solution for constantly changing configurations (sequences) with different cross-sections. The latter make it possible to map any cable configuration as a node within a range. This concept can be implemented thanks to our sequence-capable control system, which is able to operate customer-specific cable sets (KSK).

All of our systems impress with their extreme rigidity and high speed. STRUNK’s own drives guarantee optimal repositioning behavior, which achieves reliable and repeatable welding results with the shortest possible welding currents and at the same time high forces. The heat input is also low due to the short welding times.

Reliability and flexibility are important criteria for cable connections in motor vehicles. The perfect electrical conductivity must be guaranteed as well as the long-term durability of the connections.

Resistance-welded stranded connections can not only be used in the low-voltage electrical system. The high-voltage areas with their high cross-sections are also predestined for our systems. High holding forces and definable dimensions facilitate subsequent installation and laying. Cross-sections of well over 300mm² can be implemented and so, in addition to the accumulators (battery) or traction distributors, fuel cell applications can also be safely welded.
