4.10.2 One side automatic welding
When one side automatic welding is carried out
throughout the way up to the end of run-off tab plate
with a continuous trace of back bead, crack running
in longitudinal direction may, in some cases, be produced
at an area 100 ~ 150mm from the welded end.
Against such a welding failure, it is suggested that the
automatic welding is carried out in such a way that
the area of welding end vulnerable to the forementioned
failure is excluded from the object of automatic
welding for providing restraining bead either by
manual welding or C02 gas arc welding without yielding
the trace of back bead in this area.:
In cases of one side welding both by automatic
and manual methods, not only the surface bead but
also the back bead should be visually inspected and
uneven beads, if any, should be examined by nondestructive
inspection.

4.8.3.1 Butt or seam welding sequence for plates in
assembly units.
Any welding sequence convenient for welding
work may be selected as not much difference in
strength and residual stress will result from either the
transverse edge or the longitudinal edge being welded
first, as shown below.帮忙翻译一下!谢谢
