Surface Temper Weld Reinforcing Beads
Overlay Weld
GENERAL NOTES:
(a) Weld beads shown above may be deposited in any sequence that will result in placement of the beads as shown.
(b) Surface temper reinforcing beads may cover the entire weld surface, or may only be placed at the toe of the weld; they may or may not be mechanically removed.
NOTES:
(1) The distance, S , is measured from the toe of the weld to the edge of the temper beads. Measurements shall be made parallel to the base metal surface.
(2) Beads near the finished surface may be both tempering beads and surface temper reinforcing beads.

Overlap length
GENERAL NOTE: Measurement of bead overlap – % overlap length = (a − b)/a × 100%. In this figure, the shaded bead overlaps previous
bead by 30% to 40%. The distance a is measured before the next bead is deposited.
