I apologize for the putrid analogy. We're talking about flexing toward the
inside of the boat, due to water pressure. I've heard about bored sailors
stringing taut piano wire across the inside of the boat (ship?) on the
surface, just to watch it sag when they dove.

Stick or MIG welding is done single handed, freeing the other hand for beer.
Oxy/Acetylene and TIG require a long neck bottle in the feed wire hand. :-o
