The EWM forceArc welding machines and process used in the construction of renewable energy plants is both economical and environmentally friendly. The process has shown to be highly efficient in reducing production time, power and material used thus saving costs in manufacturing components for power plants. The energy-reduced, heat-minimised joining process also results in less distortion and errors during welding, improving product quality. The system can be used for manufacturing all parts of an energy plant, not limited to only certain components.
