Aluminothermic or exothermic welding – the powerweld-principle
Copper, steel, stainless steel, aluminum - these metals and their mixed compounds can be molecularly bonded together permanently, without contact resistance and without loss of quality. The metals are welded in suitable exothermic graphite molds together with metal consisting of copper and aluminum.
Powerweld -welded joints are tested according to DIN EN 61400-24 and easily meet the requirements of lightning protection class I.
Powerweld welds are possible in any desired cross section. The only requirement is that the composition and quantity of welding metal as well as the size of the welding mold be customized. Depending on the nature of the graphite, approximately 80 welds can be done with one welding mold.
Here you can see some of our standard connections.
Simply send us a request with the type of connection and the diameters or cross-sections of the conductors which should be welded. We will submit a suitable offer, including the required
We offer a complete powerweld- kit, supplied in a tool box. Containing the appropriate welding mold, 20 tubes weld metal plus all products that are required to perform a powerweld –weld.
The powerweld-kit is also available with electric ignition (battery) and with smoke filters (without smoke and sparks).
