Abstract

In this paper, we present a visualization method of weld beads for a welding training under virtual environments. To represent virtual beads, a bead shape is defined according to the datasets which consist of bead width, height, angle, penetration acquired from real welding operations. A curve equation of bead's sectional shape is mathematical modeled, and a height map is generated according to this numerical equation, which is used for generating the bead's mesh data using its height information. Finally, virtual weld beads are visualized in real-time according to the accurately simulated results from user's input motion.
