I took it as less brittle? I am not enough engineer to really know. Riveted vs welded? Poor quality rivets?
The first railroad rails vs now? Very short life
I have junked out farm machinery that was pre welding. Hot rivets.
I asked Google, lots of reading on a cold day.
Yes, it was almost always steel that was too brittle that contributed to failures. Unless it was a boiler crown sheet, nothing could keep that from blowing if you defeat enough safeties. Interesting you mention rails and rivets, a lot of machinery was riveted even after welding became more economical, because it was made with cheap re rolled rails that were too brittle to weld but good higher strength steel if riveted. Look at bed rails, riveted because it's a higher carbon stronger steel to be cheap and lightweight. |
