Optimization of porosity and surface roughness of CMT-P wire arc additive manufacturing of AA2024 using response surface methodology and NSGA-Ⅱ

Optimization of porosity and surface roughness of CMT-P wire arc additive manufacturing of AA2024 using response surface methodology and NSGA-Ⅱ

A novel cold metal transfer and pulse (CMT-P) hybrid arc technology was introduced for additive manufacturing of high-strength aluminum alloy 2024 (AA2024). The effects of process parameters, namely the wire-feed speed, travel speed, and CMT/P ratio (ratio of number of CMT stages to pulse stages in...
