This video introduces WAAM (Wire Arc Additive Manufacturing), a manufacturing technology that combines traditional welding with metal 3D printing. Instead of connecting parts, WAAM melts metal wire layer by layer, building entirely new components with minimal material waste. This approach allows for complex shapes, internal structures, and large-scale metal parts
