6.1.2 Welding
to the face plates of injected steel sandwich panels can be carried
out, provided that any effect of heat input on the elastomer does
not affect the capacity of the panel. The design documentation submitted
in accordance with Ch 1, 7.1 General is to
include details of how the effects of heat input will be addressed.
6.1.3 If pre-fabricated
panels are to be employed, welding to the face plates can be carried
out, provided that any effect of heat input on the elastomer does
not affect the capacity of the panel. The design documentation submitted
in accordance with Ch 1, 6.1 Plans to be submitted 6.1.6 is
to include details of how the effects of heat input will be addressed.
6.1.4 Minor temporary
attachments, cable trays, and small pipe clamps etc. can be welded
directly to the top or bottom plate without the use of internal reinforcing
plates. Any defects in the structure resulting from the removal of
temporary attachments are to be repaired.
6.1.5 Attention
is to be given to the examination of the plating in way of the minor
welding carried out to ensure:
-
freedom from cracks;
and
-
for each weld there
are no voids present larger than the maximum void size, see
Ch 2, 3.7 Post injection 3.7.4.
6.1.6 In areas
subject to high stress, deep penetration or full penetration welding
may be required.
