Aluminothermic or exothermic welding - the powerweld-principle!




By using the powerweld welding process it is possible to weld the connector leads directly on the pipeline or on the component which needs to be protected, e.g. a tank system or a steel construction. Powerweld is maintenance-free and independent from external energy.



Independent from external energy means that no electricity or battery connection is necessary for the powerweld welding process! The exothermic reaction starts with the aid of a spark (using a gun lighter). The welding process runs completely automatically. The result is a molecularly weld, resistance-free, corrosion-free and maintenance-free connection.
