Wire Arc additive manufacturing (WAAM) is a wire-based process that produces metal parts layer by layer using the gas metal arc welding process (GMAW). WAAM offers several advantages besides its high deposition rate (up to four kilogram per hour with steel materials), like there is no requirement for expensive special equipment; all one needs is a suitable welding system. In wire-based generative manufacturing processes such as WAAM, a laser, electron beam, or arc is used to melt a wire-shaped filler metal, which is then used to build the component. Compared to powder-based processes, WAAM benefits from the easy availability of a range of certified wires.

Fronius Robotic Cold Metal Transfer (CMT) for WAAM
The Fronius CMT (Cold Metal Transfer) welding process allows users to achieve optimum results when joining different materials. With CMT, Fronius offers a highly dynamic and cost-effective welding process with the most stable arc which generates least amount of splatter. CMT is not just ‘cold’ welding, it enables continuous regulation of heat input from cold to hot. Extremely low heat input and an exceptionally stable arc set CMT apart from conventional MIG/MAG welding. This speeds up the welding process while maintaining the weld quality which results in a wide range of applications.
