What is CMT in WAAM: Heat Accumulation Effects about?

This study investigates the effects of heat accumulation on multi-layer deposits of 316L stainless steel using Cold Metal Transfer (CMT) based Wire Arc Additive Manufacturing (WAAM). A numerical model was developed to analyze the thermal characteristics and microstructure changes during deposition, with temperature profiles measured using a pyrometer. The findings suggest a relationship between cooling rates and secondary dendrite arm spacing, providing guidelines for optimizing the manufacturing process.
