Wrong, a weld can.... be and is often... stronger than the original
metal


A
properly done fiberglass repair can be stronger than the
original... in fact, it can be a problem if you make the
patch too stiff because that throws more stress to the other
areas of the hull.

Looks to me like you guys who are already welders have a lot
of faith in metal... that's good. OTOH it would be
interesting to see your opinion after studying a text on
composite engineering. I have done minor fiberglass work for
many years, but recently decided to learn more about it &
the best books seem to be focussed on aviation.


Stainless steel is a result of composite engineering.
