In a horizontal groove weld on 10 mm material with a V-groove, the way you deposit the weld metal matters because gravity tends to cause the molten metal to sag. Using stringer beads for every fill and the final cap keeps the heat input localized, the bead narrow and well controlled, and the deposited metal from sliding out of the groove. Depositing from bottom to top gives a stable starting point at the root and a predictable buildup as you rise, which helps ensure proper penetration and a sound throat on each pass.

Weaving beads or circle passes introduce more heat and wider beads, which in a horizontal position can promote sagging, excessive buildup, or loss of groove control. A mixed pattern would create inconsistent deposition and heat distribution along the seam. So, the straight, narrow stringer beads from bottom to top provide the most reliable control for this weld configuration.
