摘要：

This paper presents a quantitative visualization analysis of flow behavior that was carried out to study flow behavior during weld-line formation. A visual mold with an obstacle pin in a plate-shaped cavity was designed, and weld-line formation was recorded for post-analysis. The main focus was on the motion behavior of the two adjacent flows originated by the obstacle pin. A particle tracking technique was used to track the melt and quantify its motion at the merging front to investigate flow behavior in orientation point of view. A micro-photography study on the cross-section of the weld-line was also carried out.
