Track welds
Splet04. jun. 2024 · The crucial parameter for multi-track welds is the overlap between the single beads. It usually can be calculated as a fraction of the width of the single bead. The literature estimates the optimal overlap distance from 0.637 (Cao et al. ) to 0.738 (Ding et al. ) times the bead width.
