Abstract

Abstract

Wire-fed metal additive manufacturing has demonstrated considerable potential for the fabrication of structural components in civil engineering because of its high deposition efficiency， high material utilization， and limited constraints on component dimensions. Demonstrative applications have been reported in a variety of engineering scenarios， including bridges， braces， structural joints， and lightweight steel structures. During wire-fed metal additive manufacturing， path planning is a critical factor affecting the surface forming quality， heat-input distribution， and mechanical properties of fabricated components. It involves several key stages， including deposition-geometry control， geometric modelling， slicing， toolpath generation， and process-parameter regulation. To systematically elucidate the fundamental principles of wire-fed metal additive manufacturing and its recent advances in engineering structures， this paper reviews existing research on path-planning methods， summarizes the latest structural engineering applications， and provides recommendations for future research and practical implementation.
