The butt welds of the doubler and bilge keel are to be full
penetration and shifted from the shell butts.
The butt welds of the bilge plating and those of the doublers
are to be flush in way of crossing, respectively, with the
doubler and with the bilge keel.
Butt welds of the intermediate flat are to be made to avoid
direct connection with the shell plating, in order that they
do not alter the shell plating, by using, for example, a copper
or a ceramic backing. |
