Gas metal arc welding (GMAW) wire arc additive manufacturing (WAAM) processes use inert shielding to protect the weld arc during material deposition, but do not protect the trailing bead, which can lead to weld issues varying from low finish quality to diminished material prop
Technologies are described directed to reducing weld additive part distortion with spot compressions integrated into the build process. The disclosed technologies can be used to make weld additive parts with potentially better geometrical accuracy.
Complex protective casings and housings are necessary for many applications, including combustion chambers of gas turbines used in aerospace engines. Manufacturing these components from forging and/or casting as a whole is challenging, costly, and time-consuming.
Compliance in a part, work holding, or base plate is beneficial for certain processes, but detrimental for machining and material removal.
In additive manufacturing large stresses are induced in the build plate and part interface. A result of theses stresses are deformations in the build plate and final component.
In wire-arc additive manufacturing and hot-wire laser additive manufacturing, wire is fed into a melt pool and melted through the arc or laser process.
