FIGURE 39.
BUTT STRAP WELDS FOR FACE
HARDENED ARMOR PLATE.
(3) To seal a crack in face hardened armor, as shown in figure
40, view A, on the following page, against spatter and to make it
watertight, weld a seal bead on the soft side and grind it flush
before applying the butt strap. All welding should be performed
on clean, scale free surfaces.
Previously deposited weld metal
should be thoroughly cleaned by chipping and wire brushing to
remove slag and oxides to ensure sound welds.
