Comparison of Properties and Bead Geometry in MIG and CMT Single Layer Samples for WAAM Applications

The process of Wire Arc Additive Manufacturing (WAAM) utilizes arc welding technology to fabricate metallic components by depositing material in a selective layered fashion. Several processes exist that can achieve this deposition strategy. Gas Metal Welding (GMAW) derived are commonly favored for their high rates (1–4 kg/h) and minimal torch reorientation required during deposition. A range GMAW available; all which have different transfer modes thermal energy input ranges the resultant structures formed from these vary mechanical properties morphology. This work will investigate single-layer parameters mode observe responses properties, bead geometry rate. selected study were Inert (MIG) Cold Transfer (CMT). Characterization parameter sets revealed relationships between travel speeds, wire feed speeds specimen proportions. Differences observed cross-sectional when comparing MIG CMT samples though influence on was less significant compared selection.
