The biggest problem with cracking on a welded ship is the welds don't stop the propagation of the crack were as when a crack reaches a riveted joint it stops. A book I read twenty or thirty years ago stated that bad welding or bad steel got the blame all the cracking on Liberty Ships happened in the same area which leads to the conclusion that the problem was bad design. The two long steel bandaids riveted to the ship to reinforce the structure where the cracking took place solved the problem and of course being riveted in the crack couldn't propagate into the bandaids.
