Multi-camera in-situ monitoring for emissivity-corrected temperature measurement in laser beam directed energy deposition

Abstract Temperature measurement is essential in metal additive manufacturing, as the spatio-thermal profile strongly influences the microstructure and therefore the key mechanical properties of the produced components. Conventional infrared thermography is widely used for in-sit...

Interpass-Temperature-Dependent Dynamic Tensile Deformation Behavior of Wire Arc Additively Manufactured 316L Stainless Steel

This study investigates the influence of interpass temperature on the dynamic tensile deformation behavior of 316L stainless steel. Specimens were fabricated using cold metal transfer (CMT)-based wire arc additive manufacturing (WAAM) at interpass temperatures of room temperature...
