1 square foot piece? Or is the weld 100% if done right?
Weld efficiency (without radiography) is typically:
butt weld = 70%
Single lap weld = 50%
But other factors can be used with inspection
or other weld designs. Double butt welds with inspection
are generally 100%, but I doubt many boatyard weld will meet pressure vessel standards in a number of regards. Additionally, corrosion
is a bit more common near welds (often in the heat affected zone next to the weld).
