Note: Aim is to overlap the existing bead 50% To 70% with proceeding bead in each layer.
Bead Sequence
The middle bead overlaps the right-hand bead by about 50% of the bead width, and that the remaining
heat-affected zone of the first bead is much smaller than the remaining heat-affected zone of the
middle bead. The left-hand bead overlaps the middle bead by about 10%, resulting in very little effect on
the heat-affected zone of the middle bead.
