This study is a fundamental investigation aimed at applying HDPE(High-Density Polyethylene), a promising alternative to FRP(Fiber-Reinforced Plastic) commonly used in hull structures, to hulls and marine structures. HDPE is well-suited for marine environments due to its excellent durability, chemical resistance, light weight, and recyclability; however, reliable joining techniques for large-scale structures remain insufficient. This research analyzes the effect of extrusion-based throughput rate conditions on weld quality. BoP(Bead-on-Plate) welding experiments were conducted using HDPE welding wire under throughput rates ranging from 0.2 to 0.7 g/sec, evaluating variations in bead shape and weight. The results showed significant changes in bead dimensions according to throughput rate, suggesting that the findings can serve as a basis for deriving optimal conditions to ensure joint quality.
