Abstract: This paper presents the benefits and challenges of using a standard robotised laser welding cell for additive manufacturing (AM). Additive manufacturing, sometimes denoted 3D-printing or rapid prototyping, has lately met strong interest in several areas of society, and a variety of technologies and materials have been in focus.
Many standard welding processes, such as gas metal arc-, laser-, or electron-beam welding, can be used for additive manufacturing (AM) with only slight adaptions. Wire-based additive manufacturing provides an interesting alternative to powder-based processes due to their simplicity and comparatively high deposition rates. The use of an electron beam as heat source for AM offers unique

TWI (The Welding Institute) states that: “Wire arc additive manufacturing uses arc welding power sources and manipulators to build 3D shapes through arc deposition. This process commonly uses wire as a material source and follows a predetermined path to create the desired shape.
Help prevent flash rusting with Wire Wizard® Rust Inhibitor additive formulated for mixing with either Blue Magic® or Blue Chill® Anti-spatter. 1 gallon (3.8 L) container is enough to mix up to 55 gallons of anti-spatter (mixing ratio depends on appliion).
Wire arc additive manufacturing is a wire-based process, and uses the gas metal arc welding process (GMAW). WAAM itself offers a nuer of advantages besides its high deposition rate (up to four kilograms per hour with steel materials).
In particular, wire arc additive manufacturing (WAAM) with gas metal arc welding (GMAW) is of high interest due to high deposition rates, material e ciency > 90% and the …
