Among the metal additive manufacturing technologies that have attracted wide attention for weight reduction, optimization, and realization of complex shapes, WAAM (Wire Arc Additive Manufacturing) using arc welding is expected to be a low-cost method that can be applied to large-scale structures.In WAAM, which is an application of this welding technology, we will introduce systems that utilize our unique arc know-how and advanced control technology at two locations: our booth and a special AM venue.
