For
horizontal welds the details
are
shown
in
Figures
25.1
through
25.8.
Note
that
a
strip
of
metal is shown
at
the
root
of the weldthis
is
known
as
the
backing strip.
Its
use
permits
the
securing
of
a
sound
root pass
without
great
diffi
culty.
In
use,
the beveled
plate edges
should be
spaced
on
the
backing
strip
and the
strip
tack
welded
to
the
plates
on
the
reverse
side.

For fillet welds
on
tee
joints
the
technique
is
shown
in
Figure
26.1. For vertical
lap joints
the
same
technique
may
be
employed notwithstanding
the difference
in
positions
of the
plates. Also,
when
depositing
a
multilayer
fillet
weld,
this
same
method would
be
used
to
deposit
the first
layer
on
both
lap
and
tee
joints.
For
depositing
sub
sequent
layers
on
tee
joints
two
means
are
used
and
are
shown
in
Figures
27.1
and
27.2. For
the
additional
layers
on
lap loints
a
somewhat similar
weave
may
be
seen
in
Figure
28.1.
